----------------------------------------------------------------
The issue is not HiveConf - that is shared. The issue is that HiveConf is
passed to JobConf which copies all values from HiveConf. So modifying HiveConf
after that has no effect on JobConf.

> Some queries are optimized so as not to create an MR job. This somehow causes
> the Configuration object in FetchOperator to be passed to the operator before
> Driver.recordValidTxns() is called. So then to this op it looks like there
> are no valid txns and it returns nothing.
