Hello,
I am testing out Hive’s LLAP functionality. My test environment is as follows:
- Hadoop 2.7.3
- Hive 2.1.1
- Tez 0.8.4
- Zookeeper 3.4.8
- Slider 0.91
I am able to get the LLAP daemon running successfully and can see it in the RM
UI. But when I start the Hive CLI and run a SELECT COUNT(*) query, the Tez DAG
fails. Following is the stack trace I found inside the container logs:
[ERROR] [main] |app.DAGAppMaster|: Error starting DAGAppMaster
java.lang.NumberFormatException: null

Can someone help me figuring out what is going wrong here?
Thanks,
