Sergey Shelukhin created TEZ-3879: ------------------------------------- Summary: potential abort propagation issue (race?) Key: TEZ-3879 URL: https://issues.apache.org/jira/browse/TEZ-3879 Project: Apache Tez Issue Type: Bug Reporter: Sergey Shelukhin
I'm looking at a Hive query where AM aborts some tasks for whatever reason (AM preemption). On the nodes, most tasks receive abort normally, like so (note that TezProcessor is part of Hive and the main class that Tez code calls; the first thing it does on any abort is log "Received abort"). {noformat} 2017-12-18T14:44:26,616 INFO [TaskHeartbeatThread ()] org.apache.tez.runtime.task.TezTaskRunner2: Attempting to abort attempt_1513367667720_3619_1_02_000012_0 due to an invocation of shutdownRequested 2017-12-18T14:44:26,621 INFO [TaskHeartbeatThread ()] org.apache.hadoop.hive.ql.exec.tez.TezProcessor: Received abort 2017-12-18T14:44:26,622 INFO [TaskHeartbeatThread ()] org.apache.hadoop.hive.ql.exec.tez.TezProcessor: Forwarding abort to RecordProcessor 2017-12-18T14:44:26,622 INFO [TaskHeartbeatThread ()] org.apache.hadoop.hive.ql.exec.tez.MapRecordProcessor: Forwarding abort to mapOp: {} MAP {noformat} However on some tasks that are terminated shortly after init, TezProcessor is never called. Moreover, when AM tries to kill the task again (when it's already running, having ignored the abort) Tez says the task is already aborted and doesn't propagate this either. {noformat} 2017-12-18T14:47:22,995 INFO [TezTR-667720_3619_3_2_12_0 (1513367667720_3619_3_02_000012_0)] reducesink.VectorReduceSinkCommonOperator: Using tag = -1 (this is the end of Hive init) ... 2017-12-18T14:47:23,133 INFO [TaskHeartbeatThread ()] org.apache.hadoop.hive.llap.daemon.impl.LlapTaskReporter: Asked to die via task heartbeat: attempt_1513367667720_3619_3_02_000012_0 2017-12-18T14:47:23,133 INFO [TaskHeartbeatThread ()] org.apache.tez.runtime.task.TezTaskRunner2: Attempting to abort attempt_1513367667720_3619_3_02_000012_0 due to an invocation of shutdownRequested (no TezProcessor log statements) {noformat} The task keeps running and the next kill is ignored {noformat} 2017-12-18T14:47:23,575 INFO [IPC Server handler 2 on 40617 ()] org.apache.hadoop.hive.llap.daemon.impl.ContainerRunnerImpl: DBG: Received terminateFragment request for attempt_1513367667720_3619_3_02_000012_0 ... 2017-12-18T14:47:23,575 INFO [IPC Server handler 2 on 40617 ()] org.apache.tez.runtime.task.TezTaskRunner2: Ignoring killTask request since the task with id attempt_1513367667720_3619_3_02_000012_0 has ended for reason: CONTAINER_STOP_REQUESTED.
