Resource Manager log error while YARN is working normally

Resource Manager log error while YARN is working normally - hadoop

I submitted the spark program to run on YARN.
The program runs normally and the yarnUI page is also displayed normally but some error logs showed in the resource manager log.

This means that the server attempted to flush out the remaining bytes to the client, but the client closed the connection before all of those bytes were sent.
This happens, fairly often with web browsers when the user navigates off the page, or closes the tab before the entire contents of the response have been send.
This happens even more often with clients that have flaky internet connections, such as mobile clients (such as when they switch towers, or go from mobile to wifi, or wifi to mobile, etc)
This also happens, with some regularity, when the client simply doesn't read the entire response and closes the connection. This often is a result of a client that isn't following the HTTP spec properly.
Example: If the client knows it is going to close the connection when it is done, it should have added the Connection: close header on the request.
The client reads the response up until it has what it wants, then closes the connection. (such as when reading JSON or XML it will read up until the JSON or XML is complete, but not any other data after it, even whitespace). This is a fact that surprises many developers using 3rd party parsing libraries. Good libraries have specific configuration options to keep reading until Soft EOF (eg: the end of the HTTP response on a persistent connection)

How to access Namenode UI with KnoxSSO

My goal
I want to access Namenode UI through KnoxSSO and browse hdfs files without Ambari.
What have I already done
I've already set up Security cluster and HDFS HA with QJM.
Apache Knox uses Pac4J provider to authenticate users with Openid Connect.
There are 3 instances of Apache Knox beyond Nginx reverse proxy.
I've also have several services working fine with KnoxSSO:
Resourcemanager UI
Jobhistory UI
WebHDFS
Apache Zeppelin
Spark History Server
The problem
Despite of all other services are accessable by their UI through knox, I can't achieve it with Namenode IU (HDFSUI).
I folowed instructions by official documentation but when I try to follow hdfsui link it's cause probably infinite loop redirecting and show: HTTP ERROR 500 java.io.IOException: Service connectivity error.
In the gateway.log file I have numerous exceptions, like these:
2022-03-19 18:15:35,509 WARN knox.gateway (IdentityAsserterHttpServletRequestWrapper.java:scrubOfExistingPrincipalParams(202)) - Possible identity spoofing attempt - impersonation parameter removed: doAs

Could anyone know, what's going wrong?

Try to add the following line for HDFSUI role in your topology file:
<version>2.7.0</version>
It should be look like this:
<service>
<role>HDFSUI</role>
<version>2.7.0</version>
<url>http://NAMENODE:50070</url>
</service>

java.lang.NullPointerException when building Firestore connection with my project id

I am trying to build a Firestore connection from my Google App Engine web application. I have followed the tutorial on google's website (https://cloud.google.com/firestore/docs/quickstart-servers) and setup the necessary service key as well as set the environment variable GOOGLE_APPLICATION_CREDENTIALS to the path of the json file with the key. However, I keep getting a NullPointerException on the line when I call the build() ater setting my project id. Has anyone encountered this same problem and have fixed it before? I can't find any similar problems online. There is not many lines of code so it seems like the problem should be relatively simple.
This is the error itself:

I have tried redoing the service key and setting the GOOGLE_APPLICATION_CREDENTIALS again through the command line. I have printed out the FirestoreOptions object and the FirestoreOptions.Builder object and those have memory addresses that are non-null. I separated each metthod call to try and see specificalyl where the error was happening and it is on the build() line. I also updated my cloud components to see if anything was out of date.
public PierMapper(String id)
{
projectId = id;
firestoreOptions = FirestoreOptions.getDefaultInstance();
System.out.println(firestoreOptions.toString());
firestoreBuilder = firestoreOptions.toBuilder();
System.out.println(firestoreBuilder.toString());
firestoreBuilder = firestoreBuilder.setProjectId(projectId);
System.out.println(firestoreBuilder.toString());
System.out.println(firestoreBuilder.build());
firestoreOptions = firestoreBuilder.build();
database = firestoreOptions.getService();
}
I need to get this connection working to Firestore so I can begin to read and write data from my webapp.

Try setting GOOGLE_APPLICATION_CREDENTIALS to the full path to your json file. I suspect your app isn't finding your key file.
You can also try using gcloud auth application-default login, as described here, instead of the env variable.

PDF parser not working in production environment

I have an application that generates some PDFs. That works in preproduction systems but not in production system. We deploy in weblogic 10.3.6, both environments are supposed to have the same configuration
We have received de OK to deploy a web-app after all functional test were made in a non productive environment. The issue is that the final PDF that the app has to create does not work in production (but in test environment, yes).
We are using:
<dependency>
<groupId>org.xhtmlrenderer</groupId>
<artifactId>core-renderer</artifactId>
<version>R8</version>
<scope>compile</scope>
</dependency>
public static void crearPDFHTML(String htmlPlantilla, OutputStream pdf)
throws Exception {
try
{
ITextRenderer renderer = new ITextRenderer();
//String plantillaLimpia = makeTidy(htmlPlantilla);
LOG.info("Antes de limpiar caracteres especiales");
String limpio = quitarCaracteresEspeciales(htmlPlantilla);
LOG.info("Antes de poner el documento en el render");
LOG.info(limpio);
renderer.setDocumentFromString(limpio);
LOG.info("antes del layout");
renderer.layout();//HERE FAILS IN PRODUCTIVE ENVIRONEMENT
LOG.info("antes de crear PDF");
renderer.createPDF(pdf);
LOG.info("PDF creado con éxito");
}catch(Throwable e)
{
e.printStackTrace();
throw new Exception(e);
}
}
If the web app works fine in pre environement, it is supposed to work the same in pro environement, and generates the PDF.

Well, finally the issue was solved. It's a quite strange situation, and I don't think this will help anyone, but....
The issue is that in DES and PRE (non- productive environements) you can take the images the PDF needs using two urls (http or https) and works with both well. But in PRO the security configuration does not allow Itext to ask for a image using http. It must use https
So that was all, just change URL configuration, the PDF works and all people is happy again.
Thanks for the answers and patience

Error when attempting to use shapefile ImageMosaic store as basis for layer

I'm trying to serve up a large number of TIF files and worldfiles through GeoServer, as an ImageMosaic store. I've followed the steps in the ImageMosaic tutorial as described here: http://docs.geoserver.org/stable/en/user/tutorials/image_mosaic_plugin/imagemosaic.html - I've pointed GeoServer at a shapefile containing the locations of the TIF files, and the shapefile is accompanied by a .prj file for the correct projection (EPSG:4326) and a .properties file that as far as I'm aware contains the correct information.
The TIF files are on another server, but the location has been added as a network drive on the GeoServer machine and the paths in the shapefile for each tile are correct.
However, when I attempt to use this store as the basis for a layer, I get the following error report (with substitutions for actual paths). The part that looks important is towards the end, where it says it's having problems visiting the directory where the imagery is stored, and after that where it says the location of the imagery is an illegal argument.

Can GeoServer not access items on network drives (without extra work) or is something else probably going on here?

How to reconnect to a persistence unit after an oracle Database failure

When I unfortunately need to restart my Oracle database (after a failure, or for any reason). My persistence unit cannot reconnect to the database (after it is up again).
Here is the error log :

EclipseLink is used in a JDBC connection Pool with Glassfish 3.1.1 .
Do you know a convenient method for the pool to reconnect automatically after losing the connection to the database ?

I think that the problem is not caused by EclipseLink but by the glassfish connection pool which you use.
The pool seems to be not aware that its connections are closed/invalid and still returning them to your application/eclipselink.
I never configured this pool, but please consult the documentation how to enable the keep alive/ verification feature within the connection pool.
This will ensure that the pool will test idle connections periodically and remove/renew them in case they are detected as invalid/closed.
