----------------------------------
Summary: Fix revert: Add new op GETFILEBLOCKLOCATIONS to WebHDFS
REST API
Key: HDFS-12459
URL: https://issues.apache.org/jira/browse/HDFS-12459
Project: Hadoop HDFS
Issue Type: Bug
Components: webhdfs
Reporter: Weiwei Yang
Assignee: Weiwei Yang
HDFS-11156 was reverted because the implementation was non optimal, based on
the suggestion from [~shahrs87], we should avoid creating a dfs client to get
block locations because that create extra RPC call. Instead we should use
{{NamenodeProtocols#getBlockLocations}} then covert {{LocatedBlocks}} to
{{BlockLocation[]}}.
