Arun Suresh commented on MAPREDUCE-5890: ---------------------------------------- [~tucu00], Yup, I did not find any better way of doing this.. I have combined the code and test case into a single patch. I have also run the test case locally varying the number of Maps and Reduces.. It works fine.. > Support for encrypting Intermediate data and spills in local filesystem > ----------------------------------------------------------------------- > > Key: MAPREDUCE-5890 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-5890 > Project: Hadoop Map/Reduce > Issue Type: New Feature > Components: security > Affects Versions: 2.4.0 > Reporter: Alejandro Abdelnur > Assignee: Arun Suresh > Labels: encryption > Attachments: MAPREDUCE-5890.3.patch > > > 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. -- This message was sent by Atlassian JIRA (v6.2#6252)
