Alan Gates commented on HIVE-7225:
----------------------------------
No. We aren't leaving these connections open for a long time. We're closing
them quite quickly at the end of each Thrift RPC. If we were leaving them open
for a long time then I would agree that it was important to close the
statements.

> There're several methods in TxnHandler where Statement (local to the method)
> is not closed upon return.
> Here're a few examples:
> In compact():
> {code}
> stmt.executeUpdate(s);
> LOG.debug("Going to commit");
> dbConn.commit();
> {code}
> In showCompact():
> {code}
> Statement stmt = dbConn.createStatement();
> String s = "select cq_database, cq_table, cq_partition, cq_state,
> cq_type, cq_worker_id, " +
> "cq_start, cq_run_as from COMPACTION_QUEUE";
> LOG.debug("Going to execute query <" + s + ">");
> ResultSet rs = stmt.executeQuery(s);
> {code}
