-------------------------------------
Summary: [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.
