Josh Elser updated HBASE-17171:
-------------------------------
Attachment: HBASE-17171.001.patch
.001 The framework sets a configuration property to control how long reads
should be executed. When writes take too long, no time remains for reads
and the user sees an error about a property they must set. We should
prevent this case and log an appropriate message.
Also fixes a rogue character in the class-level javadoc.

> Just noticed an odd error message that cropped up in some $dayjob internal
> testing.
> Sometimes, executions of IntegrationTestTimeBoundedRequestsWithRegionReplicas
> would result in an error:
> {noformat}
> Caused by: java.lang.IllegalArgumentException: Please configure
> hbase.TimeBoundedMultiThreadedReader.runtime
> at
> org.apache.hadoop.hbase.test.IntegrationTestTimeBoundedRequestsWithRegionReplicas$TimeBoundedMultiThreadedReader.<init>
> {noformat}
> After digging into the test a bit more, I realized that this is actually
> failing because the remaining time left after the writers finish (that is,
> {{hbase.IntegrationTestTimeBoundedRequestsWithRegionReplicas.runtime}} minus
> the time the writers took) was negative. So, the test harness passed a value
> which always caused this error.
> We should catch when the time available for the readers is negative and throw
> an appropriate error instructing the human to either increase the amount of
> time for
> {{hbase.IntegrationTestTimeBoundedRequestsWithRegionReplicas.runtime}} or
> decrease the amount of data written.
