----------------------------------
Summary: IntegrationTestTimeBoundedRequestsWithRegionReplicas
fails with obtuse error when readers have no time to run
Key: HBASE-17171
URL: https://issues.apache.org/jira/browse/HBASE-17171
Project: HBase
Issue Type: Bug
Components: integration tests
Reporter: Josh Elser
Assignee: Josh Elser
Priority: Minor
Fix For: 2.0.0
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.
