[HIVE-16709] LLAP: Operator abort should traverse the whole tree & cancel all Futures

• Type: Bug
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Affects Version/s: 2.1.1, 3.0.0
• Component/s: llap
• Target Version/s: 3.0.0

Description

The logs for pre-empted tasks say

Caused by: org.apache.hadoop.hive.ql.metadata.HiveException: Async Initialization failed. abortRequested=false
        at org.apache.hadoop.hive.ql.exec.Operator.completeInitialization(Operator.java:456)
        at org.apache.hadoop.hive.ql.exec.Operator.initialize(Operator.java:390)

Also for scenarios where TS -> MJ[1] -> MJ[2], the interrupt does not reach the MJ[1] operator because an exception is thrown from the MJ[2]:completeInitialization() which gets out of initializeChildren() without going over the MJ[1] futures.
