> Intermittent failure of HalfDeadTServerIT
> -----------------------------------------
>
> Key: ACCUMULO-4197
> URL: https://issues.apache.org/jira/browse/ACCUMULO-4197
> Project: Accumulo
> Issue Type: Bug
> Components: test
> Reporter: Josh Elser
> Priority: Minor
> Fix For: 1.6.6, 1.7.3, 1.8.0
>
>
> I observed an intermittent failure of HalfDeadTServerIT#testRecover today.
> This test "injects" pauses to the C read and write calls inside of tserver.
> testRecover injects a pause of 10 seconds to show that the TServer can
> reconnect to ZK (and not lose its session).
> However, with an RPC timeout of 5 seconds, if a minor compaction is
> triggered, this pause will cause a compaction to take >10 seconds which will
> trigger the "hold timeout" causing an exception to be thrown to the client.

> I believe this is intermittent based on whether or not a minor compaction is
> triggered after the i/o pausing is triggered or not. We could probably work
> around this by increasing the threshold for running a minor compaction.
