Ted Yu commented on HBASE-18541:
--------------------------------
{code}
#10 0x00007ff89d9d1ffd in [interpreted: bc = 42]
org.apache.zookeeper.ClientCnxn.submitRequest(org.apache.zookeeper.proto.RequestHeader,org.apache.jute.Record,org.apache.jute.Record,org.apache.zookeeper.ZooKeeper$WatchRegistration)
() at org/apache/zookeeper/ClientCnxn.java:1408
{code}
The above corresponds with the wait() call in ClientCnxn#submitRequest:
{code}
synchronized (packet) {
while (!packet.finished) {
packet.wait();
}
}
{code}
> [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.
