LLAPTaskSchedulerService: COMMUNICATION_ERROR"

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.

 I found one JIRA（https://issues.apache.org/jira/browse/HIVE-10649）,the problem described is quite similar  to mine.
BUT It's not as described in HIVE-10649,my cluster has four nodes and all nodes are active.
