Ajay Kumar commented on HDFS-13512:
-----------------------------------
[~shahrs87], Client should be able to see ecPolicy name whenever ec policy is
enabled. Currently when any clients lists status of hdfs dir/file using WebHdfs
where ecPolcy is enabled corresponding HdfsFileStatus object contains
un-instantiated ecPolicy (i.e null). This is because when we convert
HdfsFileStatus to Json for wiring that data we only send ecPolicyName. This
policy name is not sufficient to instantiate ecPolicy while converting this
json back to HdfsFileStatus.
> WebHdfs getHdfsFileStatus/getFileStatus doesn't return ecPolicy name wired in
> json

> 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.
