-----------------------------------------
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.
