Spring-xd strange too many open files error - spring

I upgraded from spring-xd 1.2.1 to 1.3.0, and have both under /opt on my system. After starting xd in single node (but configured to use Zookeeper), I tried to create another stream (e.g. "time | log"), and spring-xd throws the following exception:
java.io.FileNotFoundException: /opt/spring-xd-1.2.1.RELEASE/xd/config/modules/modules.yml (Too many open files)
I changed ulimit -n 60000, but it didn't solve the problem. The strange thing is why it still points to spring-xd-1.2.1.RELEASE? I have started both xd-singlenode and xd-shell under /opt/spring-xd-1.3.1.RELEASE
EDIT: add xd-singlenode running process output just to show it's pointing to 1.3.1:

have you updated your environment variables? specifically XD_CONFIG_LOCATION based on the error shown above.

org.apache.kylin.job.exception.ExecuteException: java.lang.NoClassDefFoundError: org/apache/hadoop/hive/serde2/typeinfo/TypeInfo

I find similar error on https://issues.apache.org/jira/browse/KYLIN-2511
env:
hadoop-2.7.1
hbase-1.3.2
apache-hive-2.1.1-bin
apache-kylin-1.6.0-hbase1.x-bin
I've tried copy all the hive libs to kylin, but get another ERROR.
org.apache.hadoop.mapred.YarnChild: Error running child : java.lang.NoClassDefFoundError: org/apache/hadoop/hive/serde2/typeinfo/TypeInfo
The missing class should be in hive-exec-.jar; Check and debug the "bin/find-hive-dependency.sh" to see why it wasn't able to locate this jar from your server. You can manually add it to the "hive_exec_path" variable.
BTW, Kylin 1.6 is quite old, try to upgrade to a 2.x version.
Why you just try the method mentioned in https://issues.apache.org/jira/browse/KYLIN-2511. You'd better prepare the env according to the document of v16. It is better for using the latest version of Kylin. It has more feature and fixes some bugs.

AdminTask.listTCPEndPoints('abc(abc)') throws exception: ADMF0007E: target object is required

I'm working on deploying application to WebSphere 7 using python script and the script is throwing exception at this line:-
AdminTask.listTCPEndPoints('abc(abc)')
If I run the above command before I run the python script, it works fine. It gives me an error ADMF0003E: Invalid parameter value. But the same command fails in the python script with this error:
wsadmin>AdminTask.listTCPEndPoints('abc(abc)')
WASX7015E: Exception running command: "AdminTask.listTCPEndPoints('abc(abc)')"; exception information: com.ibm.websphere.management.cmdframework.CommandValidationException: ADMF0007E: target object is required.
I can guess that there something in the python script that is causing this issue, but I don't understand why is the AdminTask.listTCPEndPoints command is not able to see the parameter being passed. I'm new to WebSphere, I have only used it in past but never configured it. Any help/insight would be highly appreciated.
Thanks!
Added stack trace of interactive mode option

Follow this link. It appears that you have not specified the target object that's why that error is coming.
I suggest use the following command as a starter
print AdminTask.listTCPEndPoints('-interactive')
Note: Instead of copying and pasting the command, type it on the command line. sometimes command editor does not take the command after pasting it directly.
Okay, I was able to fix the error. I was getting that error because as part of the application deployment script, I was copying few of my application jars to WebSphere's java/jre/lib/ext directory so that those are available in classpath. In one of those jar, I had bundled an IBM class (Base64Coder.class) which was required by a class in my jar and it was corrupting the WebSphere AdminTask utility. When I removed that Base64Coder.class from my jar, python script worked fine. I believe, the reason it corrupted WebSphere was that there was a duplication of the same class in the JVM as the class comes with IBM WebSphere installation and was present in AppServer/runtimes/com.ibm.ws.webservices.thinclient_7.0.0.jar

Oracle Data Integrator (ODI - v11.1.1.3) "unable to load language: beanshell" Error

Following an install of Eclipse 3.7.2 on my Ubuntu 12.04 development machine, I have been unable to execute any ODI packages/interfaces/procedures. On execution (for both simulated and actual runs), an error is thrown (java trace below). I am not sure if it's anything to do with the Eclipse install, but it seems likely. Does anyone have an idea how to fix this?
Also, when launching ODI from the terminal using 'bash odi', the following error is displayed in the terminal:
2013-08-15 14:43:46.162 ERROR Error during RuntimeClassLoader initialization. ODI will start without RuntimeClassLoader

After digging around for about a day on this issue, I brazenly tried running ODI as the root user on the off chance that this was a permissions issue. I started ODI from the command line (using 'bash odi') for greater verbosity, and it loaded without the error mentioned above. Something gave me the impression that this wasn't a permissions issue, but one related to the user settings.
To rectify the issue, I removed my user's odi settings folder (renaming it, for safety):
mv ~/.odi ~/.backup_odi
Then I started ODI from the terminal under my own user (i.e. not root) - there were no errors! None of my connections were available in the new settings folder though. This I fixed by closing ODI and entering the following:
cp ~/.backup_odi/oracledi/snps_login_work.xml ~/.odi/oracledi/
If anybody else encounters this issue, I hope you find this post quicker than it took me to fix it!
org.apache.bsf.BSFException: unable to load language: beanshell
The exception was thrown because bsh-2.Ob4.jar was not in the classpath and it is a dependent jar of bsf.jar

HPCC/HDFS Connector

Does anyone know about HPCC/HDFS connector.we are using both HPCC and HADOOP.There is one utility(HPCC/HDFS connector) developed by HPCC which allows HPCC cluster to acess HDFS data
i have installed the connector but when i run the program to acess data from hdfs it gives error as libhdfs.so.0 doesn't exist.
I tried to build libhdfs.so using command
ant compile-libhdfs -Dlibhdfs=1
its giving me error as
target "compile-libhdfs" does not exist in the project "hadoop"
i used one more command
ant compile-c++-libhdfs -Dlibhdfs=1
its giving error as
ivy-download:

BUILD FAILED java.net.ConnectException: Connection timed out
any suggestion will be a great help
Chhaya, you might not need to build libhdfs.so, depending on how you installed hadoop, you might already have it.
Check in HADOOP_LOCATION/c++/Linux-<arch>/lib/libhdfs.so, where HADOOP_LOCATION is your hadoop install location, and arch is the machine’s architecture (i386-32 or amd64-64).
Once you locate the lib, make sure the H2H connector is configured correctly (see page 4 here).
It's just a matter of updating the HADOOP_LOCATION var in the config file:
/opt/HPCCSystems/hdfsconnector.conf
good luck.
