[jira] [Commented] (ACCUMULO-952) Default action on `merge` command can be painful

    [ https://issues.apache.org/jira/browse/ACCUMULO-952?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13549699#comment-13549699 ] 

Keith Turner commented on ACCUMULO-952:
---------------------------------------

Could possible just make the command fail if it would create tablet with over a certain number of files.   The user could override this with the -f option maybe.

> If a user issues a merge via the shell for a table with no other arguments, this causes a table to merge down to one tablet. This can make Accumulo really unhappy, especially if the number of files for that tablet exceeds the configured threshold (100 by default?).
> Perhaps a confirmation could be added to the merge command just to make sure that the user knows what they are doing? Other ideas?
