Hue Not working with hive on tez

Explorer

Dear all 

I have installed CDP private cloud on single node, Also i added hive, hive-on-tez and Hue services but unfortunately Hue not working with hive database and hiveserver2 of hive-on-tez stopping frequently.

On hue UI this error is shown while choosing hive database

Could not connect to any of [('xx.xx.xxx.xxx', 10000)] (code THRIFTTRANSPORT): TTransportException("Could not connect to any of [('xx.xx.xxx.xxx', 10000)]",)

 

So what shall i do to work on hive using hue editor? 

thanks in advance

Hi @dv_conan 

 

As you have mentioned that hiveserver2 of hive-on-tez is stopping frequently. This seems to be the cause of this error, as this message indicates that Hive Server is down or HUE Can't reach the server.

 

Please check Hive server logs to see why the hiveserver2 on hive-on-tez is failing frequently.

It seems that Tez tar file is not uploaded to HDFS.

Can you try and manually upload the Tez tar file to HDFS manually

 

Go to CM  -> Tez  -> Actions  -> "Upload Tez tar file to HDFS.

 

Let us know if resolves your issue

I think your issue should be resolved with this posting

I have seen that solution before, but it is also not working after i added this command to /etc/hive/conf/hive-env.sh 

TEZ_JARS="/opt/cloudera/parcels/CDH/jars/tez-:/opt/cloudera/parcels/CDH/lib/tez/.jar:$CONF_DIR/tez-conf"

and then restarted the service but hivserver2 still stopping frequently

Could you please attach hive on Tez logs.

 

Please start Hive on Tez and wait till it crash completely and the provide the logs.

 

Please attach the logs from below location:

  a. /var/logs/hive

  b. /var/run/cloudera-scm-agent/process/<hove on tez>/logs

 

Please also try setting hive.server2.tez.initialize.default.sessions=false in CM  and check.
