> memory leak in directsql for mysql+bonecp specific initialization
> -----------------------------------------------------------------
>
> Key: HIVE-15551
> URL: https://issues.apache.org/jira/browse/HIVE-15551
> Project: Hive
> Issue Type: Bug
> Components: Metastore
> Affects Versions: 0.13.0
> Reporter: Xiaomin Zhang
> Assignee: Xiaomin Zhang
> Attachments: HIVE-15551.patch, HIVE-15551.patch.txt
>
>
> We observed HMS memory leak when directsql is enabled for MySQL metastore DB.
>
> The affected code is in the method MetaStoreDirecdtSql.executeNoResult():
> ((Connection)jdoConn.getNativeConnection()).createStatement().execute(queryText);
> The statement object (from createStatement()) is unfortunately referenced in
> the Connection object. Although close() is called on the Connection object
> in finally block, the BoneCP just moves it to a freeConnection list. Hence,
> statement object never get chances to be closed.
> The leaked statement object is not huge (~1KB as observed in memory
> analyzer). However long running Hive Metastore Server is very likely ended up
> with bad performance doing frequent garbage collection.
