Subject [DISCUSS] HDFS roadmap/wish list
Date Mon, 10 Jun 2019 17:08:03 GMT

I am soliciting feedbacks for HDFS roadmap items and wish list in the
future Hadoop releases. A community meetup
is happening soon, and perhaps we can use this thread to converge on things
we should talk about there.

I am aware of several major features that merged into trunk, such as RBF,
Consistent Standby Serving Reads, as well as some recent features that
merged into 3.2.0 release (storage policy satisfier).

What else should we be doing? I have a laundry list of supportability
improvement projects, mostly about improving performance or making
performance diagnostics easier. I can share the list if folks are

Are there things we should do to make developer's life easier or things
that would be nice to have for downstream applications? I know Sahil Takiar
made a series of improvements in HDFS for Impala recently, and those
improvements are applicable to other downstreamers such as HBase. Or would
it help if we provide more Hadoop API examples?
