Mate Juhasz updated OOZIE-3575:
-------------------------------
Issue Type: Improvement (was: Bug)
> Add credential support for cloud file systems
> ---------------------------------------------
>
> Key: OOZIE-3575
> URL: https://issues.apache.org/jira/browse/OOZIE-3575
> Project: Oozie
> Issue Type: Improvement
> Components: core
> Affects Versions: 5.2.0
> Reporter: Mate Juhasz
> Assignee: Mate Juhasz
> Priority: Major
> Fix For: trunk
>
>
> Oozie by default gathers delegation tokens for the nodes defined in
> _mapreduce.job.hdfs-servers_ (or _oozie.launcher.mapreduce.job.hdfs-servers_
> in case of distcp actions) and for the workflow path.
> Though this implementation is good for hdfs, we dont support occasions where
> the job related resources, which we want to access in runtime are present on
> different file systems/buckets etc...
> The HDFSCredentials class should be revised to handle getting tokens for
> different cloud storages.
> *The following scenarios should be addressed:*
> Oozie should obtain delegation token in case
> * the defaultFs is cloud
> * the workload.xml is in cloud
> * input/output/auxiliary files referred from workflow are in cloud
> * (newly introduced feature) user could define filesystem credentials for the
> workflow (as its done with hive/hcat etc..) -> this would allow the user to
> handle the situation where Oozie could not decide which tokens are needed at
> launch time by default and could also get tokens for different cloud storages
> and buckets as well
> Example for credentials addition:
> {noformat}
> <credential name="aws_auth" type="filesystem">
> <property>
> <name>filesystem</name>
> <value>s3a://qe-s3-bucket-mst</value>
> </property>
> </credential>
> {noformat}
