---------------------------------------
Summary: Job Credentials are not transmitted if security is turned
off
Key: MAPREDUCE-4554
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4554
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: job submission, security
Reporter: Benoy Antony
Assignee: Benoy Antony
Credentials (secret keys) can be passed to a job via
mapreduce.job.credentials.json or mapreduce.job.credentials.binary .
These credentials get submitted during job submission and are made available to
the task processes.
In HADOOP 1, these credentials get submitted and routed to task processes even
if security was off.
In HADOOP 2 , these credentials are transmitted only when the security is
turned on.
This should be changed for two reasons:
1) It is not backward compatible.
2) Credentials should be passed even if security is turned off .
