Naveen Gangam updated HIVE-7021:
--------------------------------
Description:
The number of the following objects keeps increasing if a query causes an
exception:
org.apache.hive.service.cli.HandleIdentifier
org.apache.hive.service.cli.OperationHandle
org.apache.hive.service.cli.log.LinkedStringBuffer
org.apache.hive.service.cli.log.OperationLog
The leak can be observed using a JDBCClient that runs something like this
connection =
DriverManager.getConnection("jdbc:hive2://" + hostname + ":10000/default", "",
"");
statement = connection.createStatement();
statement.execute("CREATE TEMPORARY FUNCTION
dummy_function AS 'dummy.class.name'");
The above SQL will fail if HS2 cannot load "dummy.class.name" class. Each
iteration of such query will result in +1 increase in instance count for the
classes mentioned above.
This will eventually cause OOM in the HS2 service.
