Subject [jira] [Commented] (ACCUMULO-456) Need utility for exporting and importing tables
Date Tue, 13 Mar 2012 15:40:39 GMT


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.
