-------------------------------------------------------------------
Thanks for your explanation and updating the patch, [~hemanthboyina].
After applying [^HDFS-15063.002.patch], users can execute GETFILESTATUS of
WEBHDFS REST API against HttpFS server. But it still fails when users use
{{WebHdfsFileSystem#getFileStatus()}} against HttpFS server. I confirmed it
with adding the following codes to the bottom of testECPolicy().
{code:java}
WebHdfsFileSystem httpfsWebHdfs = (WebHdfsFileSystem) FileSystem.get(new
URI("webhdfs://" + TestJettyHelper.getJettyURL().toURI().getAuthority()),
TestHdfsHelper.getHdfsConf());
HdfsFileStatus httpfsFileStatus =
(HdfsFileStatus)httpfsWebHdfs.getFileStatus(ecFile);
assertNotNull(httpfsFileStatus.getErasureCodingPolicy()); // This should
succeed.
{code}
This is because the return value of {{FSOperations#toJsonInner}} doesn't have
{{ecPolicyObj}} and {{JsonUtilClient#toFileStatus}} can't get the ecPolicy
information. Could you check it?

> Currently LISTSTATUS call to HttpFS returns a json. These jsonArray elements
> have the ecPolicy name.
> But when HttpFsFileSystem converts it back into a FileStatus object, then
> ecPolicy is not added
