---------------------------------------
Summary: TxnHandler should use PreparedStatement to execute direct
SQL queries.
Key: HIVE-20607
URL: https://issues.apache.org/jira/browse/HIVE-20607
Project: Hive
Issue Type: Bug
Components: Standalone Metastore, Transactions
Affects Versions: 4.0.0
Reporter: Sankar Hariappan
Assignee: Sankar Hariappan
Fix For: 4.0.0
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.
