We are trying to install Phoenix 4.4.0 on HBase 1.0.0-cdh5.4.4 (CDH5.5.5 four nodes cluster) via this installation document: Phoenix installation
Based on that we copied our phoenix-server-4.4.0-HBase-1.0.jar to hbase libs on each region server and master server, so that, on each /opt/cloudera/parcels/CDH-5.4.4-1.cdh5.4.4.p0.4/lib/hbase/lib folder in the master and three region servers.
After that we reboot the HBase service via Cloudera Manager.
Everything seems to be ok, but when we are trying to access to phoenix shell via ./sqlline.py localhost command, we get a Zookeeper error in that way:
15/09/09 14:20:51 WARN client.ZooKeeperRegistry: Can't retrieve clusterId from Zookeeper
org.apache.zookeeper.KeeperException$ConnectionLossException: KeeperErrorCode = ConnectionLoss for /hbase/hbaseid
So we are not sure that the installation is properly done. Is necessary any further configuration?
We are not even sure wether we are using the sqlline command properly.
Any help will be appreciated.
After reinstalling the 4 nodes cluster on AWS, phoenix is now working properly.
It's a pitty that we don't know exactly what was really happening, but we think that after several changes in our config, we broke something that made phoenix impossible to work.
One thing to take into consideration is that sqllline command has to be executed with an ip that is in the zookeeper quorum, and this is something we were doing wrong, since we were trying to run it from the namenode, and it wasn't in the zookeeper quorum.Once we run sqlline.py from a datanode, everything is working fine.
Btw, the installation guide that we finally followed is Phoenix Installation

I followed the tutorialshttp://hadoop.apache.org/docs/r2.4.1/hadoop-project-dist/hadoop-common/SingleCluster.html and installed hadoop 2.4.1 as pseudo distributed cluster. I created a ubuntu VM using OracleVM and installed hadoop as mentioned in the link. It was setup fine and able to run the examples. However the job tracker URL is not working. :50030 gives page not found. I also tried netstat on the server and there is no process waiting on 50030 port . Do i need to start any other service ? What are the possible reasons ?
You need to execute this:
$HADOOP_HOME/sbin/mr-jobhistory-daemon.sh start historyserver
Or JobTracker won't start.
(In my case, $HADOOP_HOME is in /usr/local/hadoop)
Check the value of mapred.job.tracker.http.address in mapred-site.xml
If the port is different, use that.
Also check if jobtracker is running. Check the jobtracker logs.
You need to enter the following command
http://localhost:50030/
Job Tracker web UI.
I am new to the spark, After installing the spark using parcels available in the cloudera manager.
I have configured the files as shown in the below link from cloudera enterprise:
http://www.cloudera.com/content/cloudera-content/cloudera-docs/CM4Ent/4.8.1/Cloudera-Manager-Installation-Guide/cmig_spark_installation_standalone.html
After this setup, I have started all the nodes in the spark by running /opt/cloudera/parcels/SPARK/lib/spark/sbin/start-all.sh. But I couldn't run the worker nodes as I got the specified error below.
[root#localhost sbin]# sh start-all.sh
org.apache.spark.deploy.master.Master running as process 32405. Stop it first.
root#localhost.localdomain's password:

When I run jps command, I got:

32405 Master
28148 DataNode
7852 Main

I couldn't run the worker node properly. Actually I thought to install a standalone spark where the master and worker work on a single machine. In slaves file of spark directory, I given the address as "localhost.localdomin" which is my host name. I am not aware of this settings file. Please any one cloud help me out with this installation process. Actually I couldn't run the worker nodes. But I can start the master node.
Thanks & Regards,
bips
Please notice error info below:
localhost.localdomain: at java.lang.ClassLoader.loadClass(libgcj.so.10)
I met the same error when I installed and started Spark master/workers on CentOS 6.2 x86_64 after making sure that libgcj.x86_64 and libgcj.i686 had been installed on my server, finally I solved it. Below is my solution, wish it can help you.
It seem as if your JAVA_HOME environment parameter didn't set correctly.
Maybe, your JAVA_HOME links to system embedded java, e.g. java version "1.5.0".
Spark needs java version >= 1.6.0. If you are using java 1.5.0 to start Spark, you will see this error info.
Try to export JAVA_HOME="your java home path", then start Spark again.
I installed the hadoop 2.2 system on my ubuntu box using this tutorial
http://codesfusion.blogspot.com/2013/11/hadoop-2x-core-hdfs-and-yarn-components.html
Everything worked fine for me and now when I do
http://localhost:50070
I can see the management UI for HDFS. Very good!!
But the I am going through another tutorial which tells me that there must be a task manager UI running at http://mymachine.com:50030 and http://mymachine.com:50060
on my machine I cannot open these ports.
I have already done
start-dfs.sh
start-yarn.sh
start-all.sh
is something wrong? why can't I see the task manager UI?
You have installed YARN (MRv2) which runs the ResourceManager. The URL http://mymachine.com:50030 is the web address for the JobTracker daemon that comes with MRv1 and hence you are not able to see it.
To see the ResourceManager UI, check your yarn-site.xml file for the following property:
yarn.resourcemanager.webapp.address
By default, it should point to : resource_manager_hostname:8088
Assuming your ResourceManager runs on mymachine, you should see the ResourceManager UI at http://mymachine.com:8088/
Make sure all your deamons are up and running before you visit the URL for the ResourceManager.
For Hadoop 2[aka YARN/MRV2] - Any hadoop installation version-ed 2.x or higher its at port number 8088. eg. localhost:8088
For Hadoop 1 - Any hadoop installation version-ed lower than 2.x[eg 1.x or 0.x] its at port number 50030. eg localhost:50030
By default HadoopUI location is as below
http://mymachine.com:50070
I've configured hadoop 1.0.4 in pseudo-distributed mode. Everything's good, I can put local files in HDFS and run wordcount task. But I just can't access the jobtracker web UI through localhost:50030, localhost:50070 doesn't work neither.
HTTP ERROR 404
Problem accessing /jobtracker.jsp. Reason:
/jobtracker.jsp Powered by Jetty://
I look at the log files, but there's no error...
I used to have some problem with datanode, and jobtracker complained about replication, but that is solved and now all daemons are good (namenode, datanode, jobtracker, tasktracker, secondarynamenode) and no error in any of the log files.
Any suggestions?
Ok finally I solved it myself, I had to re-install the system then re-install hadoop. I think the problem should be that I've previously installed the CDH4 on my system, which is hadoop 2.0.0 and even if I uninstalled all of its packages (debian system) and change the tmp folder of HDFS, but maybe there's still something left. The only way is to restart over.
I have been struggling to install CDH via tarball, there is no document that describes the steps or guides through. I do have root access on the server & wish to install CDH4 via tarball in Pseudo mode. Can anyone help?. On the same server apache hadoop is also installed, i want to install this CDH, without effecting the existing apache hadoop.
It will not work..because in the end CDH4 will use the same ports which your existing apache hadoop is using..It will work ..if you shutdown your existing hadoop cluster and then start your CDH4 cluster. Or else change all the port numbers for namenode,secondary namenode,jobtracker, tasktracker and datanode and their respective web UI's port..which is kind of tedious.. It would be also helpful if you provide some error logs..So I can highlight what exactly is the problem.
