[jira] [Created] (HADOOP-10357) Memory Leak in
UserGroupInformation.doAs for JDBC Connection to Hive
Larry McCay created HADOOP-10357:
------------------------------------
Summary: Memory Leak in UserGroupInformation.doAs for JDBC Connection to Hive
Key: HADOOP-10357
URL: https://issues.apache.org/jira/browse/HADOOP-10357
Project: Hadoop Common
Issue Type: Bug
Components: security
Affects Versions: 1.2.0
Reporter: Larry McCay
When using UGI.doAs in order to make a connection there appears to be a memory leak involving the UGI that is used for the doAs and the UGI held by TUGIAssumingTransport.
When using this approach to establishing a JDBC connection in an environment that will serve many users and requests client side eventually runs out of memory.
