Subject Some block can not be found while inserting data into HBase
Date Tue, 27 May 2014 11:25:05 GMT
I put massive records into HBase and found that one of the region servers
crashed. I checked the RS log and NameNode log and found them complaining
that some block does not exist.

For example:

*In RS's log:*
java.io.IOException: Bad response ERROR for block

Was the fact that one HDFS block does not exist that caused the RS to
crash? Why would a block missing?
