> Project: HBase
> Issue Type: Bug
> Reporter: stack
> Priority: Minor
>
> On our internal rig we got the below. The test times out waiting on the
> preempted worker tasks to go up:
> ZKUtil.setData(zkw, task, slt.toByteArray());
> waitForCounter(SplitLogCounters.tot_wkr_preempt_task, 1, 2, WAIT_TIME);
> I see the preempt come in and get logged but at same time, the task has
> completed in about the timeout time:
> 2014-04-13 22:38:26,868 WARN [RS_LOG_REPLAY_OPS-TestSplitLogWorker-1]
> handler.HLogSplitterHandler(87): task execution prempted task
> 2014-04-13 22:38:26,868 INFO [RS_LOG_REPLAY_OPS-TestSplitLogWorker-1]
> handler.HLogSplitterHandler(107): worker svr,1,1 done with task
> /hbase/splitWAL/task in 1504ms
> We timed out before the preempt got to up the counter. Let me keep an eye
> on these...... Will up timeout and add more logging if we see this again.
