Colm O hEigeartaigh commented on HIVE-20607:
--------------------------------------------
Thanks [~kgyrtkirk] , but as it's a security issue why wouldn't we just
backport the fix to a supported release branch? Users are not going to switch
to an alpha release in production.

> TxnHandler uses direct SQL queries to operate on Txn related databases/tables
> in Hive metastore RDBMS.
> Most of the methods are direct calls from Metastore api which should be
> directly append input string arguments to the SQL string.
> Need to use parameterised PreparedStatement object to set these arguments.
