I cannot get into ambari hive view, I get the following errors. I have restarted HS2 and hive metastore, webHcat server couple of times. It does not fix the problem. Webhcat failed to start after the install (not sure if webhcat server has to do something with the hive view, files view and Tez view). I can run a job from hive shell successfully.

@Praneender Vuppala

I wonder if you are hitting this issue: https://issues.apache.org/jira/browse/AMBARI-15727, probably not. You can try setting Hive queries to MR instead of Tez to see if the problem still exists.

Can you provide more information about your environment? What version of Ambari are you using? What version of HDP?

You said you can run a query from the hive shell. Are you use the "hive" or the "beeline" client. The hive client talks to the metastore directly. The beeline client uses the thrift server and uses more of the overall stack.

Here is the documentation for the beeline client: https://cwiki.apache.org/confluence/display/Hive/HiveServer2+Clients#HiveServer2Clients-BeelineExamp...

I tried that too. I dont get user impersonation error but i still get nullpointerexception

@Praneender Vuppala

Is the Thrift Server running?

@Michael Young

First of everything, when i get into hive view i get the null pointer error. It is not letting run anything from hive view. I changed the execution engine to mr, I still get the same issue. Its a 2 node cluster and I am using ambari 2.2.2.0 and HDP - 2.4.2.0. I am using hive client to talk to the metastore. Let me know if you need anything else.

Thanks

@Praneender Vuppala

Can you try using the beeline client to run the same queries that you run via the hive client? I'm curious if that works, as the communication mechanism is different.

Praninder · ‎09-14-2016

@Michael Young

I am able to connect via beeline client can execute the queries pretty much same as from hive client.

@Praneender Vuppala

You can take a look at the Ambari Server logs to see if you can get more information about the errors:

/var/log/ambari-server/ambari-server.log

@Michael Young

I am running java 1.8.0_101. The link you pointed hortonworks community has a solution saying "java update to 1.8.0.71 fixed the issue". Do you think 1.8.0_101 should be degraded to 1.8.0.71. Is that a good practice?

Thanks

myoung · ‎09-14-2016

What version of java are you running? Type

java -version

Are you using OpenJDK or Oracle? Did you install it manually? Or did you install it via yum?

This link walks you through the process of changing your JDK for HDP: https://docs.hortonworks.com/HDPDocuments/Ambari-2.2.1.1/bk_ambari_reference_guide/content/ch_changi...

Praninder · ‎09-14-2016

It started working. All i did is to restart the ambari-agents and ambari-server.

Thanks for the help @Michael Young
