Subject [jira] [Commented] (ACCUMULO-1053) continuous ingest detected data loss
Date Tue, 19 Feb 2013 15:35:12 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-1053?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13581369#comment-13581369

Eric Newton commented on ACCUMULO-1053:
---------------------------------------

Keith writes on the dev list:

bq. Seems like this loop should be moved to isRead() part of repo.  This has two advantages.
 It does not tie up a Fate thread.  Also if lots of leases need to be recovered it can cycle
through all of them calling recoverLease once, instead of waiting for each one to be done.
Maybe this would spin up a lot of parallel work in the namenode

I agree: I'll refactor the code.

> Now that we're logging directly HDFS, we added datanodes to the agitator. That is, we
are now killing data nodes during ingest, and now we are losing data.
