Subject [jira] [Commented] (ACCUMULO-2793) Clean up handling of moving HDFS under Accumulo from non-HA to HA
Date Tue, 15 Jul 2014 20:16:06 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-2793?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14062585#comment-14062585
] 

Keith Turner commented on ACCUMULO-2793:
----------------------------------------

I think {{hdfs://namenode.example.com:8020/accumulo}} should be removed from the value of
{{instance.volumes}}.  Also may be worth add the following comment to the site snippet.

{code:xml}
    <!-- instance.dfs.uri and instance.dfs.dir should not be set-->
    <property>
      <name>instance.volumes</name>
      <value>hdfs://nameservice1/accumulo</value>
    </property>
    <property>
      <name>instance.volumes.replacements</name>
      <value>hdfs://namenode.example.com:8020/accumulo hdfs://nameservice1/accumulo</value>
    </property>
{code}

> We added a util to handle cluster maintenance (such as going from non-HA HDFS to HA HDFS)
in ACCUMULO-1832.
> It should be added to section 13.5 Tools in the user manual, and a reference to that
section should be added in the section 12 explanation of the impact of supporting multi-volume
setups.
