    [ https://issues.apache.org/jira/browse/HIVE-6852?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15459144#comment-15459144 ] 

Shawn Lavelle commented on HIVE-6852:
-------------------------------------

This workaround doesn't seem to work with authentication set to CUSTOM.  Client still hangs.

> I've noticed that when there is an underlying issue in connecting a client to the JDBC interface of the HiveServer2 to run queries, you get a hang after the thrift portion, at least in certain scenarios: 
> Turning log4j to DEBUG, you can see the following when trying to get a connection using:
> {noformat}
>         Connection jdbc = DriverManager.getConnection(this.con,"hive","password");
>         "jdbc:hive2://localhost:10000/default",
> {noformat}
> The logs get to here before the hang :
> {noformat}
