      Description

      When I tried to run this script agains 0.96 cluster i got this error:

      $ hbase org.jruby.Main region_status.rb
      NameError: uninitialized constant IOException
        const_missing at org/jruby/RubyModule.java:2647
               (root) at region_status.rb:104
      

      This line is causing issue:

      table = HTable.new config, '.META.'.to_java_bytes
      

      I belive this should be changed to:

      table = HTable.new config, 'hbase:meta'.to_java_bytes
      

      Second issue was caused by this line

      server_count = MetaScanner::allTableRegions(config,$tablename.to_java_bytes,false).size()
      

      MetaScanner.allTablesRegion() is changed in 0.96 so i changed few lines in order to fix this:

      if not $tablename.nil?
       # Creating TableName object
        $TableName = HTableDescriptor.new($tablename.to_java_bytes).getTableName()
      end
      while true
        if $tablename.nil?
          server_count = admin.getClusterStatus().getRegionsCount()
        else
          #Creating HConnection object
          connection = HConnectionManager::getConnection(config);
          server_count = MetaScanner::allTableRegions(config, connection, $TableName ,false).size()
        end
        print "Region Status: #{server_count} / #{meta_count}\n"
      

      After this changes script is working against 0.96. Since i'm far away from expert in jruby can someone review this fix ? I will attach patch.
