--------------------------------------
Thanks [[email protected]]. The branch-1 is using old way of HTable's
deprecated APIs, so it is fine.
> Use a shared thread pool for AtomicityWriter, AtomicGetReader,
> AtomicScanReader's connections in TestAcidGuarantees

> AtomicityWriter, AtomicGetReader, AtomicScanReader creates connection inside,
> since the thread pool is not shared, by default each connection will create
> 256 threads. If there are 5 AtomicityWriters, 1 AtomicGetReader, and 1
> AtomicScanReader, it will create lots of threads and causes max user
> processes to be reached, and OOME. Use a share thread pool to work around
> this issue.
