    [ https://issues.apache.org/jira/browse/HBASE-6642?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13442368#comment-13442368 ] 

rajeshbabu commented on HBASE-6642:
-----------------------------------

This problem is because below code in disable_all.rb
{code}
        regex = /^#{regex}$/ unless regex.is_a?(Regexp)
        list = admin.list.grep(regex)
        count = list.size

{code}
in case of * regex will become ^*$ which is valid in Ruby and admin.list.grep(regex) gives all available tables.
But same expression(^*$) in Java returns empty list.
{code}
        failed = admin.disable_all(regex)
        puts "#{count - failed.size} tables successfully disabled"
        puts "#{failed.size} tables not disabled due to an exception: #{failed.join ','}" unless failed.size == 0
{code}
Even the number of tables to disabled is zero, output is "#{count - failed.size} tables successfully disabled".
This is applicable for enable_all and drop_all also.
