Hbase hbck -repair slow
We recently suffered meta corrupt issue. We tried to use hbck -repair to fix
But the performance is not fast (about 1 region for 1 second). Are there any better way to speed up the process?
Btw, My Hbase is 0.90.6. Thanks.

If you have only lost your META, I would just use:
hbase hbck -fixMeta -fixAssignments
This will rebuild your META

Kevin
Thanks for the update. Actually you can think of the whole meta is missing , or say deleted.
Can multiple hbck repair table run at the same time ?

Lashing,
Without knowning the exact errors you are seeing it would be hard to make
recommendations. If it is just META that is messed up you can use:
hbase hbck -fixMeta -fixAssignments
I think(not sure) in that version you can do
hbase hbck -repair <tablename>
This will let you target a specific table to speed up the repair process.
