----------------------------------
Issue Type: Improvement (was: Bug)
> Streaming API TransactionBatch.beginNextTransaction() does not wait for locks
> -----------------------------------------------------------------------------
>
> Key: HIVE-12421
> URL: https://issues.apache.org/jira/browse/HIVE-12421
> Project: Hive
> Issue Type: Improvement
> Components: HCatalog, Transactions
> Affects Versions: 0.14.0
> Reporter: Eugene Koifman
> Assignee: Eugene Koifman
>
> TransactionBatchImpl.beginNextTransactionImpl() has
> {noformat}
> LockResponse res = msClient.lock(lockRequest);
> if (res.getState() != LockState.ACQUIRED) {
> throw new TransactionError("Unable to acquire lock on " + endPt);
> }
> {noformat}
> This means that if there are any competing locks already take, this will
> throw an Exception to client. This doesn't seem like the right behavior. It
> should block.
> We could also add TransactionBatch.beginNextTransaction(long timeoutMs) to
> give the client more control.
