> 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.
