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?
