Subject [jira] [Commented] (ACCUMULO-683) Accumulo ignores HDFS max replication configuration
Date Mon, 16 Jul 2012 21:14:34 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-683?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13415640#comment-13415640
] 

John Vines commented on ACCUMULO-683:
-------------------------------------

Unless there are any objections, I'm going to implement this as an initialization time prompt
which will check both max and mins and ask for what setting the user wants IFF the default
of 5 is not within bounds.
