Description

When current oss master hive tries to bring up the LLAP Application Master, it fails with this issue :

This is because llap_server uses templates.py yarnfile to bringup the LLAP Application Master which has the placement_policy as "NODE". Hadoop has started using 2.12.7 jackson version which has issues in parsing NODE to either [node, rack]. Therefore it is not able to cast the placement policy correctly.

 

Resolution :

We will have to send placement_policy as "node" from the templates.py of Hive Llap Server module. Will raise a PR for this issue :
