--------------------------------------------------------------------
Looked into this a little deeper and realized that HIVE-13335 changed
{{TxnStore.TIMED_OUT_TXN_ABORT_BATCH_SIZE}} from 1000 to 50000. The test
{{TestDbTxnManager.testLockTimeout}} is using this value to create 50017 locks
and waiting for some time so that they expire. This is causing the test batch
to time-out since it takes very long time. The test batch timeout currently is
40 min and it takes a lot longer than that.

> Pre-commit jobs are failing currently due to out of disk space. The issue is
> happening due to huge size of hive.log when TestDbTxnManager test fails or
> times-out. When this test fails or times-out Ptest tries to persist these
> logs for debugging. Since this test has been timing out frequently, this
> accumulates a lot of these log files and eventually Ptest server runs of disk
> space. Each run of TestDbTxnManager is generating ~30 GB of hive.log. I tried
> to run it locally and it quickly reached 7 GB until I had to cancel it.
> The issue seems to be coming from this code block in TxnHandler.java
> {noformat}
> if(LOG.isDebugEnabled()) {
> LOG.debug("Locks to check(full): ");
> for(LockInfo info : locks) {
> LOG.debug(" " + info);
> }
> }
> {noformat}
> We should either change it trace or change the log mode of this test to INFO
> so that it generates smaller log files.
