HBase exception after upgrading from hbase-0.90-branch to trunk

Thu, 11 Aug 2011 11:56:02 -0700

First of i had problem with .META. table, shell and thrift said that i dont have this table, but hbase operating almost normal and all regions were online, but i cannot make ICV, so i had stoped hbase and removed -ROOT- and .META. after starting hbase again and running add_table.rb on all tables and restarting hbase again i get a lot of this errors:
