Subject ShortCircuitWhat does OP_READ_BLOCK mean?
Date Thu, 31 Jan 2013 00:31:34 GMT

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

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

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?
