Comment 3 for bug 1404430

The current limitation of IPC completion logic is not proper to handle messages from different Cli contexts. Recent code drops for query cancellation exposed this limitation but it could also happen with ESPs. So far, the problem is only with JDBC T2 driver.

Suggested work-around is to set env variable SQL_NO_REGISTER_CANCEL to 1 (export SQL_NO_REGISTER_CANCEL=1), then run the phoenix T2 test.

Lower the "Importance" to high while working on the fix.
