[jira] [Commented] (OODT-335) Allow for some Resource Manager
operations to act on groups of jobs based upon Metadata key-value pairs
[ https://issues.apache.org/jira/browse/OODT-335?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13127228#comment-13127228 ]
Gabe Resneck commented on OODT-335:
-----------------------------------
I should add that one thing required for this task is to make metadata available to the RM. I feel that the best place to put the metadata (or rather, the best place to provide access to the metadata) is in the JobInput implementation, as this allows the project developer to negotiate the manner in which Metadata is stored and accessed.
The upshot of all of this is that the JobInput interface must be extended to include a method that allows access to job metadata and the implementation will define how this access take place.

> While performing operations (such as prioritizing a job or flagging it to not be scheduled) upon specific jobs is well and good, it is not a very powerful tool. Many times, operators want to perform these functions on groups of jobs, specifically, groups that share a key-value pair of metadata. For example, this would allow an operator to move all jobs with the value "10/18" for the metadata key "date".
