Arun Suresh commented on MAPREDUCE-5890: ---------------------------------------- [~chris.douglas], So, if our objective is to have CryptoUtils contained, and since it is currently being used only by the mapped framework, I'd prefer it remains where it is : in {{hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-core/src/main/java/o/a/h/mapreduce/task/crypto/}} else It looks like the only other place it fits in is {{./hadoop-common-project/hadoop-common/src/main/java/o/a/h/crypto/}} in which case, it will look like a more generic utility and we will invite more people using it before it becomes stable. I'd rather move it over once it stabilizes > 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-5890.10.patch, MAPREDUCE-5890.11.patch, > MAPREDUCE-5890.12.patch, MAPREDUCE-5890.13.patch, MAPREDUCE-5890.3.patch, > MAPREDUCE-5890.4.patch, MAPREDUCE-5890.5.patch, MAPREDUCE-5890.6.patch, > MAPREDUCE-5890.7.patch, MAPREDUCE-5890.8.patch, MAPREDUCE-5890.9.patch, > org.apache.hadoop.mapred.TestMRIntermediateDataEncryption-output.txt, > syslog.tar.gz > > > 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.
