Eric Yang commented on YARN-9581:
---------------------------------
[~Prabhu Joseph] There is a bug in WebResource that it doesn't pass header
correctly in some conditions. This was discovered in YARN-8869, and also
explained in [this
blog|https://juristr.com/blog/2015/05/jersey-webresource-ignores-headers/].
Can you revise the WebResource instances to use Builder class instead? Thanks
