-----------------------------------------

             Summary: [READ] Report multiple locations for PROVIDED blocks
                 Key: HDFS-12778
                 URL: https://issues.apache.org/jira/browse/HDFS-12778
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Virajith Jalaparti
            Priority: Major


On {{getBlockLocations}}, only one Datanode is returned as the location for all 
PROVIDED blocks. This can hurt the performance of applications which typically 
3 locations per block. We need to return multiple Datanodes for each PROVIDED 
block for better application performance/resilience.
