Subject [jira] [Commented] (ACCUMULO-981) support pluggable encryption codecs for MapFile when recovering write-ahead logs
Date Tue, 12 Mar 2013 20:09:15 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-981?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13600415#comment-13600415

Keith Turner commented on ACCUMULO-981:
---------------------------------------

bq. Drat, worth a shot

Its something to think about.  The fact that is not a 1:1 mapping, just means it not dead
simple.  Your comments here and Eric's comments on 1085 hint that we may need to rethink the
what the output of log sort is inorder to solve a few issues for 1.6.

> As with ACCUMULO-980, we need to support encryption for the recovered write-ahead logs
that are stored as MapFiles in HDFS. Those MapFiles need to support low-latency seeks, so
aligning the encryption with the block compression is a good strategy.
