Subject [jira] [Updated] (HBASE-18894) null pointer exception in list_regions in shell command
Date Thu, 28 Sep 2017 23:33:02 GMT

     [ https://issues.apache.org/jira/browse/HBASE-18894?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Mike Drob updated HBASE-18894:
------------------------------
    Attachment: HBASE-18894-v3-master.patch

The first seven warnings are repeated and show up as new because line numbers shifted I think.
The last two in rubocop are actually new and straightforward to fix.

/testptch/hbase/hbase-shell/src/main/ruby/shell/commands/list_regions.rb:167:9: C: Use a guard
clause instead of wrapping the code inside a conditional expression.
/testptch/hbase/hbase-shell/src/main/ruby/shell/commands/list_regions.rb:173:21: C: Use `each_value`
instead of `each`.

Attaching a patch that addresses them as well.
