Rushabh S Shah commented on HDFS-13512:
---------------------------------------
{quote}ListStatus is already among the slowest calls for Hdfs.
{quote}
This is what we do in {{DistributedFileSystem}}. Can't think of a reason why it
should be different for {{WebhdfsFileSystem}}.
Also not comfortable adding multiple ec-related members in HdfsFileStatus class.
> 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.
