Ajay Kumar commented on HDFS-13512:
-----------------------------------
[~shahrs87] the goal is that any users of webHdfsFileSystem should be able to
retrieve the EC policy from the returned HdfsFileStatus object. Initial patch
was work around to get at least the name without increasing redundancy.
> WebHdfs getFileStatus doesn't return ecPolicy

> Currently LISTSTATUS call to WebHdfs returns a json. These jsonArray elements
> do have the ecPolicy name.
> But when WebHdfsFileSystem converts it back into a FileStatus object, the
> ecPolicy is not added. This is because the json contains only the ecPolicy
> name and this name is not sufficient to decode it back to ErasureCodingPolicy
> object.
> While converting json back to HdfsFileStatus we should set ecPolicyName
> whenever it is set for give file/dir.
