Hive LLAP Vertex failure

Hi, We have 4 node HDP cluster installed, 3 data nodes and 1 namenode. I have enabled Hive LLAP for low latency queries but its behavior is strange, for example when I try to execute a simple count query it works fine but the same query fails on executing again with following error message. Error Message ERROR : Status: Failed ERROR : Vertex re-running, vertexName=Map 1, vertexId=vertex_1563258949712_0034_51_00 ERROR : Vertex re-running, vertexName=Map 1, vertexId=vertex_1563258949712_0034_51_00 ERROR : Vertex failed, vertexName=Map 1, vertexId=vertex_1563258949712_0034_51_00, diagnostics=[Vertex vertex_1563258949712_0034_51_00 [Map 1] killed/failed due to:OWN_TASK_FAILURE, Vertex vertex_1563258949712_0034_51_00 [Map 1] failed as task task_1563258949712_0034_51_00_000004 failed after vertex succeeded.] ERROR : DAG did not succeed due to VERTEX_FAILURE. failedVertices:1 killedVertices:0 Detailed Error Message ERROR : FAILED: Execution Error, return code 2 from org.apache.hadoop.hive.ql.exec.tez.TezTask.

I have tweaked many setting after reading countless articles but none of them are helping me to resolve the issue. A little help or hint towards right direction would be great. ... View more
