Subject: version mismatch exception
Hi Guys
I changed the endkey of one of the records in the '.META.' table because
of the chaining issue we experienced , using the program which gets
that row and does a put so that the endkey could be changed , now when
I try to view the record in .META. table using shell I get a
ERROR: org.apache.hadoop.io.VersionMismatchException: null
The master is also down and I can't bring this up , it is throwing an
exception:--
