ShortCircuitWhat does OP_READ_BLOCK mean?
Hi,

When I do an hbase hbck, I'm getting this:

13/01/30 19:29:55 WARN hdfs.DFSClient: Failed to connect to
/192.168.23.7:50010, add to deadNodes and continuejava.io.IOException:
Got error for OP_READ_BLOCK, self=/192.168.23.7:57612,
remote=/192.168.23.7:50010, for file
/hbase/entry/df36c172b5b6523467eb676b70e94e26/.regioninfo, for block
-6941943399693151592_200976

Any idea what it means?

I'm getting many errors like that, and when I'm trying to run MR jobs,
I'm getting 2013-01-30 16:58:59,575 INFO
org.apache.hadoop.hbase.regionserver.HRegionServer: Scanner
1275691821504852773 lease expired on region....

Can it be related?

Thanks,

JM
