Description

The problem is two fold:

• FetchTask.initialize, which is called during parsing of the query, converts the HiveConf it is given into a JobConf by copying it.
• Driver.recordValidTxns, which runs after parsing, adds the valid transactions to the HiveConf.

Thus fetch operators will use the transactions from the previous command.
