> Ambari seems to issue a formal shutdown to a Region server but quickly (30 seconds) follows it up with SIGKILL. On a full loaded HBase system with about 200 regions per region server and active transaction flow, there is no way a RS can stop in 30 seconds. This has caused many issues in production including a memstore corruption. Why not use the shutdown script that comes with HBase?
