Ted Yu commented on HBASE-18541:
--------------------------------
Sometimes the retry-test ended with:

However, AsyncRpcRetryTest.TestFailWithOperationTimeout passes when run
individually.
> [C++] Segfaults from JNI

> Key: HBASE-18541
> URL: https://issues.apache.org/jira/browse/HBASE-18541
> Project: HBase
> Issue Type: Sub-task
> Reporter: Enis Soztutar
> Assignee: Ted Yu
>
> retry-test and multi-retry-test fails flakily when run with
> {code}
> buck test --all --no-results-cache
> {code}
> or when run in a loop:
> {code}
> for i in `seq 1 10`; do buck test --no-results-cache core:retry-test || break
> 1; done
> {code}
> The problem seems to be within the JNI internals and usually happens at the
> create table method call. I was not able to inspect much, but the comments in
> our mini-cluster indicate that we may need to use global references instead
> of local ones. I suspect the problem happens when there is a GC run for the
> test since the failure happens usually after some time (but almost always in
> create table method).
> [~ted_yu] do you mind taking a look at this.
