[jira] [Commented] (ACCUMULO-456) Need utility for exporting and importing tables

["Keith Turner (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ACCUMULO-456?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13228454#comment-13228454 ] 

Keith Turner commented on ACCUMULO-456:
---------------------------------------

The following steps would partially accomplish this.

 * Clone table
 * Disable bulk imports
 * Compact table
 * Take table offline
 * Wait for Accumulo GC to clean up files in table dir
 * Distcp files
 * Bulk import files on remote cluster

There are two reasons to compact.
 * Tablets can reference files that extend beyond tablet range and contain stale data.
 * Tablets can point to files in other table dirs as a result of cloning.

The above procedure does not copy existing table configuration stored in zookeeper or the tables split points.
