Subject [jira] [Resolved] (ACCUMULO-952) Default action on `merge` command can be painful
Date Thu, 10 Jan 2013 15:34:13 GMT


Eric Newton resolved ACCUMULO-952.

    Resolution: Fixed
      Assignee: Eric Newton  (was: Billie Rinaldi)

I added a prompt if the user provides no arguments to control merging, which merges the whole
table.  Apparently this is surprising to people. :-)

> 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?
