Description

I see this occasionally on a linux vm. vjasani .. you might have an idea why this is going on (this is your test I believe and a recent addition). If you have stuff I can try, shout.

Here is fail:

org.junit.ComparisonFailure: expected:<client_1[0]> but was:<client_1[4]>
   at org.apache.hadoop.hbase.regionserver.slowlog.TestSlowLogRecorder.confirmPayloadParams(TestSlowLogRecorder.java:97)
   at org.apache.hadoop.hbase.regionserver.slowlog.TestSlowLogRecorder.testOnlieSlowLogConsumption(TestSlowLogRecorder.java:178)

Here is log:
