hemanthboyina commented on HDFS-6874:
-------------------------------------
have tried to implement get_block_locations in HttpFS , but facing an issue
Webhdfs when calls getblocklocations , NN sends LocatedBlocks and webhdfs
parses this locatedblocks.
+HttpFswithWebHDFS+ :
httpfsfilesystem when calls client for getblocklocations , httpfs recieves
BlockLocations[] as client converts the Locatedblocks (which was recieved from
NN ) to BlockLocations[] .
so httpfs sends BlockLocations[] to webhdfs and webhdfs expects LocatedBlocks
and fails to parse
any suggestions [~elgoiri] ?
