Hi, all:
I want to test hive LLAP performance in my cluster:
Hive2.3.0,hadoop2.7.1,tez0.9.2. While tez task always fails to schedued by
tez am task, after looking into tez am log, I found many suspect informations
like this one :
"[TaskSchedulerEventHandlerThread] |tezplugins.LlapTaskSchedulerService |:
Processing de-allocate request for
task=attempt_1564973659067_0002_1_00_000000_0, state=ASSIGNED,
endReason=COMMUNICATION_ERROR"
Does someone know what's that mean?Thanks. Maria.
