(info) there was a delay in deletion of EPHEMERAL znode in zookeeper

["dong.yajun" <do...@gmail.com>]

Hi,

I want to know the EPHEMERAL znode get deleted has a delay about 30s in
zookeeper ?


In out hbase cluster, If an active master is down, the hmaster will be
started from the standby master which take over the active role in about
30s, is this normal ?

Looks like you are using 0.94.x

See HBASE-5926 Delete the master znode after a master crash

Cheers

Yes the ephemeral node will generally be deleted after the session timeout
which is probably configured to 30s in your cluster. This link talks about
hbase zookeeper configs:
