Subject [jira] [Commented] (MAPREDUCE-5890) Support for encrypting Intermediate data and spills in local filesystem
Date Sat, 28 Jun 2014 13:54:25 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-5890?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14046863#comment-14046863
] 

Alejandro Abdelnur commented on MAPREDUCE-5890:
-----------------------------------------------

LGTM. 

One minor nit (i can take care of it when committing), in {{JObSubmitter.java#copyAndConfigureFiles()}}
javadoc, line 295 no needed change.

[~chris.douglas], I believe all our suggestions/concerns have been addressed. Do you want
to do a new pass on the patch?

I'll wait a few days to commit.

> For some sensitive data, encryption while in flight (network) is not sufficient, it is
required that while at rest it should be encrypted. HADOOP-10150 & HDFS-6134 bring encryption
at rest for data in filesystem using Hadoop FileSystem API. MapReduce intermediate data and
spills should also be encrypted while at rest.
