The exception originated from Web UI corresponding
to HBaseAdmin.listTables().
At that moment, master was unable to process the request - it needed some
more time.

Hi, ted,
Thanks for your reply!!
I found the log in l-namenode2.dba.cn8 during the restarting progress:
2015-05-15 12:11:36,540 INFO [master:l-namenode2:6]
master.ServerManager: Finished waiting for region servers count to settle;
checked in 5, slept for 4511 ms, expecting minimum of 1,
bq. the backup master take over at 2015-05-15 12:16:40,024 ?
The switch of active master should be earlier than 12:16:40,024 - shortly
after 12:15:58
l-namenode1 would do some initialization (such as waiting for region
servers count to settle) after it became active master.
I tried to download
After l-namenode1 became active master , it assigned regions:
2015-05-15 12:16:40,432 INFO [master:l-namenode1:6]

hi, TED,
Any idea?
When the HMaster restart, how can i know when it is really can handle
request from application? is there any mark in logs?

@Ted,
plz see the log from 12:11:29 to 12:15:28, this timerange the HMaster is
in
In the period you identified, master was assigning regions.
e.g.
2015-05-15 12:13:09,683 INFO
[l-namenode2.dba.cn8.qunar.com,6,1431663090427-GeneralBulkAssigner-0]
master.RegionStates: Transitioned {c634280ce287b2d6cebd88b61accf685
state=OFFLINE, ts=1431663189621, server=null} to
OK, you can get the log from

Can you check server log on 192.168.39.22
http://l-namenode2.dba.cn8.qunar.com/192.168.39.22:6 ?
That should give you some clue.

hi,ted,
Thanks very much!
Namenode process was not running on l-namenode2.dba.cn8(192.168.39.22),
just HMaster run on it。
So you means that at 2015-05-15 12:15:04, the HMaster is handling two
region server down, and not
ready to handle client request? And how can i tell when the HMaster is
bq. the HMaster is handling two region server down, and not ready to handle
client request?
I didn't mean that - for a functioning master, handling region server
shutdown is part of the master's job.
You should see something similar to the following in (functioning) master
