> regionserver crashed,it is too long time to notify hmaster.when hmaster know regionserver's shutdown,it is long time to fetch the hlog's lease.
> hbase is a online db, availability is very important.
> i have a idea to improve availability, monitor node to check regionserver's pid.if this pid not exsits,i think the rs down,i will delete the znode,and force close the hlog file.
> so the period maybe 100ms.
