Master ticket for Hadoop 0.23 integration
Assigining to you since the two remaining tickets are assigned to you.
Here's the JIRA for downstream components: BIGTOP-162. It is specifically couched in the terms of MR2 rather than any specific Hadoop release.
And this is only about hadoop, not downstream.
I couldn't find any from a cursory search
Is this just for HDFS + YARN + MR2? We've already got an existing umbrella JIRA for downstream integration with Hadoop 0.23 APIs.
