Subject Data Locality and WebHDFS
Date Sun, 16 Mar 2014 22:07:01 GMT
Hi all,

I'm writing up a Google Summer of Code proposal to add HDFS support to
Disco, an Erlang MapReduce framework.

We're interested in using WebHDFS.  I have two questions:

1) Does WebHDFS allow querying data locality information?

2) If the data locality information is known, can data on specific data
nodes be accessed via Web HDFS?  Or do all Web HDFS requests have to go
through a single server?
