kanaka kumar avvaru updated HDFS-8686:
--------------------------------------
Status: Patch Available (was: Open)
The reason for the issue is {{WebHdfsFileSystem#getXAttr(Path p, final String
name)}} is doing a second lookup via {{JsonUtilClient}} with the user passed
string "USER.attr1" which is un-neccessary as the NN has already given filtered
Xattribute.
Attached patch to correct the code with different method to pickup value
directly from response json map.
> WebHdfsFileSystem#getXAttr(Path p, final String name) doesn't work if domain
> name is in bigcase
