Arpit Agarwal commented on HDFS-13512:
--------------------------------------
Thanks for the patch [~ajayydv]. Could you please a couple of test cases just
for HdfsFileStatus to verify that:
# If policy is present but ecPolicyName is null, then non-null name is returned.
# If policy is absent, and ecPolicyName is present, then non-null name is
returned.
# If both are null, then null is returned.
> 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.
