Re: [DISCUSS] Merge HDFS-9806 to trunk

2017-12-05 Thread Sean Mackrory
I'm generally supportive of a merge - unless anyone brings up new concerns,
I've been happy with the design, implementation and discussion and it seems
to be at a good checkpoint.

When you get to writing the site documentation - one thing in particular I
think should be called out early in the description of the feature is the
need to create a read-only namespace specific to the remote storage. I can
see this getting merged and more than a few people wanting to know how they
can dynamically mount their remote storage on their existing HDFS cluster
today :)

[DISCUSS] Merge HDFS-9806 to trunk

2017-12-03 Thread Chris Douglas
Hey hdfs-dev@-

The HDFS-9806 dev branch is getting ready to merge to trunk. This branch
adds a new storage type (PROVIDED) to support reading remote data as HDFS
blocks. Design documentation and discussion are available on JIRA [1].

Over the next week or so, we'll work through the remaining issues, write
the site documentation, and generally clean up the branch. The current code
has been stressed in experimental settings, including a large production
benchmark. When this feature is not enabled and active, it should have no
effect on HDFS. The merge will checkpoint progress on reading remote data
through HDFS, setting up work on the write path [2] and improving usability.

Please look over the branch and raise issues that should be addressed
before the merge. -C
