      Description

      While running ATS stress tests, 15 concurrent ATS reads (python thread which gives ws/v1/time/TEZ_DAG_ID, ws/v1/time/TEZ_VERTEX_DI?primaryFilter=TEZ_DAG_ID:<dag_id> etc) calls.

      Note: Summary store for ATSv1.5 is RLD, but as we for each dag/application ATS also creates leveldb cache when vertex/task/taskattempts information is queried from ATS.

      Getting following type of excpetion very frequently in ATS logs :-
