Re: regionserver restart ERROR
HI,
   when issue 'balancer',  'false' returned.
  below is error log:

  hbase> get 't1', "key\x03\x3f\xcd"
  hbase> get 't1', "key\003\023\011"
  hbase> put 't1', "test\xef\xff", 'f1:', "\x01\x33\x40"

The HBase shell is the (J)Ruby IRB with the above HBase-specific commands
added.
For more on the HBase Shell, see
http://hbase.apache.org/docs/current/book.html

ERROR: wrong number of arguments (1 for 0)

Here is some help for this command:
Trigger the cluster balancer. Returns true if balancer ran and was able to
tell the region servers to unassign all the regions to balance  (the
re-assignment itself is async).
Otherwise false (Will not run if regions in transition).
hbase(main):003:0> balance_switch true
true

0 row(s) in 0.0140 seconds

hbase(main):004:0> balancer
false

0 row(s) in 0.0060 seconds

   maybe regions 'not run if regions in transition'. how to know wheather
the region is 'in transition' status or not? any cli?

  Many Thanks!
