------------------------------
Summary: JDBC client connections hang at TSaslTransport
Key: HIVE-6852
URL: https://issues.apache.org/jira/browse/HIVE-6852
Project: Hive
Issue Type: Bug
Components: JDBC
Reporter: jay vyas
I've noticed that when 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}
