Lefty Leverenz commented on HIVE-13249:
---------------------------------------
Doc note: Added TODOC1.3 and TODOC2.1 labels for the new configuration
parameters *hive.max.open.txns* and *hive.count.open.txns.interval*. They will
need to be documented in the wiki for 1.3.0 and 2.1.0 (but not 2.0.x).

> 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.
