[jira] [Comment Edited] (SPARK-5682) Add encrypted shuffle in spark
[ https://issues.apache.org/jira/browse/SPARK-5682?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14611527#comment-14611527 ]

---------------------------------------------------------
steps were added to encode and decode the data, the performance will not be fast than before, in the same time, codes also have security issue, for example save the plain text in configuration file and finally used as the part of the key
in the same time, the feature based on hadoop 2.6, it is the limitation, that is why i said rely on hadoop
though it is public stable, however, you cannot ensure if the api will not be changed since it was not the comercial software.

> Encrypted shuffle is enabled in hadoop 2.6 which make the process of shuffle data safer. This feature is necessary in spark. AES is a specification for the encryption of electronic data. There are 5 common modes in AES. CTR is one of the modes. We use two codec JceAesCtrCryptoCodec and OpensslAesCtrCryptoCodec to enable spark encrypted shuffle which is also used in hadoop encrypted shuffle. JceAesCtrypoCodec uses encrypted algorithms jdk provides while OpensslAesCtrCryptoCodec uses encrypted algorithms openssl provides.
> Because ugi credential info is used in the process of encrypted shuffle, we first enable encrypted shuffle on spark-on-yarn framework.
