> Hard upper bound on number of open transactions
> -----------------------------------------------
>
> Key: HIVE-13249
> URL: https://issues.apache.org/jira/browse/HIVE-13249
> Project: Hive
> Issue Type: Improvement
> Components: Transactions
> Affects Versions: 2.0.0
> Reporter: Wei Zheng
> Assignee: Wei Zheng
> Attachments: HIVE-13249.1.patch, HIVE-13249.2.patch,
> HIVE-13249.3.patch, HIVE-13249.4.patch, HIVE-13249.5.patch, HIVE-13249.6.patch
>
>
> 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.
