[jira] [Commented] (MAPREDUCE-4551) Key Protection : Add ability
to read keys and protect keys in JobClient and TTS/NodeManagers
[ https://issues.apache.org/jira/browse/MAPREDUCE-4551?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13565423#comment-13565423 ]
Daryn Sharp commented on MAPREDUCE-4551:
----------------------------------------
A few questions:
* Why aren't the credentials used as intended to store each secret individually? Joining the keys and values with a comma may be subject to issues if either contains a comma.
* Why is credentials fetching secrets from the system env?

> Project: Hadoop Map/Reduce

> Based on Cluster configuration, NodeManager/TaskTrackers set up Decrypters to decrypt the job's secrets.
> Based on Job configuration, JobClient reads secrets from a KeyStore using a Keyprovider implementation and encrypts them using the cluster's public key.
> The encrypted secrets are stored in Job Credentials.
> The task addresses the following requirements:
> • Plug in different key store mechanisms.
> • Retrieve specified keys from a configured keystore as part of job submission
> • Protect keys during its transport through the cluster.
> • Make sure that keys are handed over only to the tasks of the correct job.
