Subject [jira] [Resolved] (ACCUMULO-434) Bulk import should use more robust mechanism to give work to tablet servers
Date Wed, 19 Dec 2012 20:13:13 GMT

     [ https://issues.apache.org/jira/browse/ACCUMULO-434?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Eric Newton resolved ACCUMULO-434.
----------------------------------

    Resolution: Won't Fix

Not really a problem anymore.  The retry code picks a random server, and the bulk import timeout
is now configurable.  Also, there's a lot of defensive code to deal with re-importing a file
multiple times. Reopen if this becomes a problem in the future.

> Bulk import currently selects a random tablet server and ask it do the bulk import work.
 If the connection times out it assumes the tablet server failed even though the tablet server
may still be working on the bulk import.  Work was done in ACCUMULO-422 to make this problem
much less likely in 1.4.  For 1.5 we need to redesign this.
