Hi, HBasers!
We are running a small (4 nodes) staging HBase cluster and have got stuck
in a strange state: we got our 'page' table not in any "boolean" state:
HBase Shell; enter 'help<RETURN>' for list of supported commands.
Type "exit<RETURN>" to leave the HBase Shell
Version 0.92.1-cdh4.0.0, rUnknown, Mon Jun 4 17:25:27 PDT 2012
hbase(main):001:0> is_enabled 'page'
false
0 row(s) in 0.6310 seconds
hbase(main):002:0> is_disabled 'page'
false
0 row(s) in 0.0420 seconds
*hbase hbck* does not report inconsistencies:
...
page is okay.
Number of regions: 183
Deployed on: hbase02dev.303net.pvt,60020,1345151162063
hbase03dev.303net.pvt,60020,1345151153104
hbase04dev.303net.pvt,60020,1345151152636
...
0 inconsistencies detected.
Status: OK
Now we are blocked to update schema for this table since we cannot disable
it for '*alter table*':
hbase(main):003:0> disable 'page'

But we cannot enable it to leave this state:

Data fromt the table is still available.
We tried restarting whole cluster, restarting Zookeeper. Nothing helped to
fix it. Did anybody have such issue?
I would appreciate on any help how to fix it.
