Subject [jira] [Commented] (ACCUMULO-409) Failed bulk import files are copied through master
Date Thu, 21 Jun 2012 23:05:42 GMT


Keith Turner commented on ACCUMULO-409:

I found something interesting while looking into this.  Tablet servers currently copy failures
and then the master copies them.  This copy by the tserver is not something that we could
rely on to happen, it does not help fix this problem in anyway.  Its duplicate effort that
needs to be removed.  Its an artifact of using the old bulk import code in FATE.

Also, its possible that a tablet server could copy something into the failed dir, then a later
import attempt by the master could succeed.  This would result in an unnecessary file in the
failed dir.

> When bulk import fails, the failed files are copied into a fail dir by the master.  This
is very bad if its a large amount of data.  Noticed this while debugging ACCUMULO-408.
