Subject [jira] [Commented] (ACCUMULO-1963) Rename metadata table ID (!0) so it doesn't have an exclamation point
Date Tue, 25 Feb 2014 18:48:22 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-1963?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13911878#comment-13911878
] 

Mike Drob commented on ACCUMULO-1963:
-------------------------------------

If the underlying file system supports symbolic links, it might be nice to link from {{tables/!0}}
to whatever we the new directory is, concurrent with the rename, in case users have custom
ops scripts.

> The table ID for the metadata table is problematic. The reserved character requires special
escaping in shells, like bash.
> This was going to happen with ACCUMULO-1712, but would require some effort to upgrade
and test the root table, walogs, and HDFS paths, so this is going to be postponed and not
completed for 1.6.
> The proposed new table ID is "\+m", following the conventions of the root table, whose
ID is "\+r". ("\+" can be used much more safely across filesystems and shells).
