[jira] [Commented] (ACCUMULO-981) support pluggable encryption codecs for MapFile when recovering write-ahead logs

    [ https://issues.apache.org/jira/browse/ACCUMULO-981?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13600343#comment-13600343 ] 

John Vines commented on ACCUMULO-981:
-------------------------------------

I know that this is a bit roundabout, but I'm wondering if it would be easier to make the files used for recovery RFiles with the Mutation being transformed to a Key and the columns being written as either one large value or a series of values (using other Key properties to order)

> 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.
