MAPREDUCE-7371. DistributedCache alternative APIs should not use DistributedCache APIs internally #3855

virajjasani · 2022-01-04T16:11:34Z

Description of PR

DistributedCache has been deprecated long back and it's still being used as of today. However, all the alternative Job APIs (for deprecated DistributedCache APIs) still internally use DistributedCache APIs only, this is a deadlock and it leaves no room for removal of DistributedCache APIs in future. We should move core logic to Job or JobContext as required and let deprecated DistributedCache APIs point to the right alternatives internally.

How was this patch tested?

Does the title or this PR starts with the corresponding JIRA issue id (e.g. 'HADOOP-17799. Your PR title ...')?

@jojochuang @aajisaka @tasanuma Could you please take a look?

tasanuma · 2022-01-07T01:22:06Z

@virajjasani It makes sense to me. We might want to copy the javadocs from DistributedCache to Job and JobContextImpl as well.

virajjasani · 2022-01-07T05:56:48Z

Oh yes, makes sense. Let me put all the Javadocs. Thanks @tasanuma

tasanuma · 2022-01-07T10:00:20Z

Thanks for updating it. +1, pending Jenkins.
