Subject HBase exception after upgrading from hbase-0.90-branch to trunk
Date Thu, 11 Aug 2011 18:54:44 GMT
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:
