Chaoyu Tang commented on HIVE-10732:
------------------------------------
[~xuefuz] The stmtHandle in HiveQueryResultSet can be set from HiveStatement or
HiveDatabaseMetaData. If the variable "statement" in HiveQueryResultSet is not
null, the stmtHandle was from HiveStatement, otherwise from
HiveDatabaseMetaData. In method close(), patch#0 closes HiveStatement
stmtHandle(TOperationHandle) using s.closeClientOperation(), and close the
already closed TOperationHandle again using closeOperationHandle(), so we see
such exceptions in the failed tests.
But patch#1 closes HiveStatement stmtHandle once by s.closeClientOperation(),
and closes HiveDatabaseMetaData stmtHandle by closeOperationHandle().
> Hive JDBC driver does not close operation for metadata queries

> In following file
> http://github.mtv.cloudera.com/CDH/hive/blob/cdh5-0.14.1/jdbc/src/java/org/apache/hive/jdbc/HiveQueryResultSet.java
> Line 315 implemented the ResultSet.close() method. Because "DatabaseMetadata"
> operation doesn't have a statement, it doesn't "close" the operation.
> However, regardless whether it has a statement or not, it should close the
> operation through the "stmtHandle".
