[jira] [Created] (ARROW-1320) hdfs block locations

Martin Durant created ARROW-1320:
------------------------------------

             Summary: hdfs block locations
                 Key: ARROW-1320
                 URL: https://issues.apache.org/jira/browse/ARROW-1320
             Project: Apache Arrow
          Issue Type: Improvement
            Reporter: Martin Durant


To provide a function which can return the set of machines on which the data blocks of a given hdfs file are stored. This is best for scheduling systems (e.g., dask) which can move the computation to the machine which has the data, and so cut out network data traffic.
