Hbase Migration Error

[Peeyush Bishnoi <pe...@yahoo-inc.com>]

Hello All ,

Got following error while upgraded the Hbase from hadoop 0.15.3 to
hadoop 0.16.0 . But the Hbase is working fine through shell as i can
create the table. But my previous data in Hbase can't able to recover
due migration failure : 

[peeyushb@hbase2
hbase]$ /home/peeyushb/hadoop/src/contrib/hbase/bin/hbase migrate
upgrade
08/02/27 16:15:26 INFO util.Migrate: Verifying that file system is
available...
08/02/27 16:15:26 INFO util.Migrate: Verifying that HBase is not
running...
08/02/27 16:15:26 INFO ipc.Client: Retrying connect to
server: /10.66.80.79:60000. Already tried 1 time(s).
08/02/27 16:15:27 INFO ipc.Client: Retrying connect to
server: /10.66.80.79:60000. Already tried 2 time(s).

Please tell me why it is so and how can i recover my data in Hbase
tables...

Those errors are due to the Migration tool trying to connect
to the master (and, if your HBase cluster is not running,
which is correct) it will retry for about a minute or so before
deciding that the master is not available and the migration
can proceed. By default it will retry 5 times at 10 second
intervals.
