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.

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.

      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 ?

If you have only lost your META, I would just use:

hbase hbck -fixMeta -fixAssignments

This will rebuild your META
