Subject "compact" command cannot trigger major compaction
Date Fri, 21 Feb 2014 09:40:38 GMT
Hi Folks

I'm trying to trigger a major compaction in my HBase cluster with 16 data
nodes, in the shell command, i input the following command:

hbase> compact 't1'


But it seems doesn't work, what i got from MASTER log is as below, nothing
more, :

And in the HBASE UI "Table Attributes" list, Compaction --> NONE, guys, any
idea? Thanks.

Cheers
