Work Description: jojochuang opened a new pull request #3322:
URL: https://github.com/apache/hadoop/pull/3322
### Description of PR
This is a rebase of the patch file 11 attached to HDFS-6874.
The GETFILEBLOCKLOCATIONS is HCFS compatible. Add support of it to httpfs to
makes it possible for more applications to run directly against HttpFS server.
Add GETFILEBLOCKLOCATIONS op support for httpfs server (HttpFSServer). Add
the same for httpfs client (HttpFSFileSystem)
Let webhdfs client (WebHdfsFileSystem ) tries the new GETFILEBLOCKLOCATIONS
op if the server supports it. Otherwise, fall back to the old
GET_FILE_BLOCK_LOCATIONS op. The selection is cached so the second invocation
doesn't need to trial and error again.
### How was this patch tested?
Unit tests.
