In HBase land we've pretty well discovered that we'll need to have the same version of protobuf that the HDFS/Yarn/MR servers are running. That is to say there are issues with ever having 2.4.x and 2.5.x on the same class path. Upgrading to 2.5.x would be great, as it brings some new classes we co

This is being targeted for release 2.3. 2.1.x release stream is for stabilizing. When it reaches stability, 2.2 GA will be released. The current features in development will make it to 2.3, including HDFS-2832. On Thu, Aug 8, 2013 at 2:04 PM, Matevz Tadel wrote: > Thanks Colin, I subscribed to

There is work underway to decouple the block layer and the namespace layer of HDFS from each other. Once this is done, block behaviors like the one you describe will be easy to implement. It's a use case very similar to the hierarchical storage management (HSM) use case that we've discussed befor
