EOFException in hbase

Any idea if this can be fixed with out loseing data or why it would happen?


Master logs keeps trying to assign the regions but the region server keeps 
filing with the error below.

Re: EOFException in hbase

Posted by stack <st...@duboce.net>.
Did you update your hbase and use data written by a previous version of 
hbase?  If so, I'd guess the EOF is because of the incompatible changes 
listed in CHANGES.txt.  Otherwise, anything earlier in the log 
complaining of failed writes to hdfs?
