> checkCmdOnDriver(driver.compileAndRespond("insert into R select * from S where a in (select
a from T where b = 1)"));
>     txnMgr.openTxn("three");
>     txnMgr.acquireLocks(driver.getPlan(), ctx, "three");
>     locks = getLocks();
>     Assert.assertEquals("Unexpected lock count", 3, locks.size());
>     checkLock(LockType.SHARED_READ, LockState.ACQUIRED, "default", "T", null, locks.get(0));
>     checkLock(LockType.SHARED_READ, LockState.ACQUIRED, "default", "S", null, locks.get(1));
>     checkLock(LockType.SHARED_READ, LockState.ACQUIRED, "default", "R", null, locks.get(2));
> {noformat}
> This test case is failing. The expected order of locks is supposed to be T, S, R. But
upon closer inspection, it seems to be R,S,T. 
> I'm not much familiar with what these locks are and why the order is important. Raising
this jira so while I try to understand it all. Meanwhile, if somebody can explain here, would
be helpful.
