Vihang Karajgaonkar updated HIVE-16213:
---------------------------------------
Attachment: HIVE-16213.02.patch
Thanks for the review [~spena] and [~stakiar]. I was adding a test case as
suggested by Sahil in the review and I found a few more places in the code
where the query can leak. Updating the second version of the patch.
> ObjectStore can leak Queries when rollbackTransaction throws an exception

> Key: HIVE-16213
> URL: https://issues.apache.org/jira/browse/HIVE-16213
> Project: Hive
> Issue Type: Bug

> In ObjectStore.java there are a few places with the code similar to:
> {code}
> Query query = null;
> try {
> openTransaction();
> query = pm.newQuery(Something.class);
> ...
> commited = commitTransaction();
> } finally {
> if (!commited) {
> rollbackTransaction();
> }
> if (query != null) {
> query.closeAll();
> }
> }
> {code}
> The problem is that rollbackTransaction() may throw an exception in which
> case query.closeAll() wouldn't be executed.
> The fix would be to wrap rollbackTransaction in its own try-catch block.
