Subject java.io.EOFException while starting HBase
Date Mon, 18 Aug 2008 12:24:11 GMT
I've just came across this msg while starting hbase on 3 node cluster.
Formatting hadoop namenode helped.
But I still wonder what could cause this error msg.
It's seems that -ROOT- is corrupted. Am I right? What could be the cause?
