Wei Zheng commented on HIVE-13249:
----------------------------------
The Exception being caught from startHouseKeeperService is thrown by the class
instantiation:
{code}
openTxnsCounter = (HouseKeeperService)c.newInstance();
{code}
But I think I can move this line into the try block, and make this method not
throw exception, so that we can best effort. I don't think we want to fail all
txns just because we cannot start the counter service.
> Hard upper bound on number of open transactions

> We need to have a safeguard by adding an upper bound for open transactions to
> avoid huge number of open-transaction requests, usually due to improper
> configuration of clients such as Storm.
> Once that limit is reached, clients will start failing.
