Or Anything wrong?

Are you a supported Hortonworks customer? If yes, then you should not do this and reach out to Hortonworks support. You should not apply patch. Hortonworks support team keeps a track of which customers are on what patch so future help can be provided based on what version and additional patches you have.

If you are not a Hortonworks customer, I still don't recommend but you can try applying the patch in dev/test and see if it resolves your problem.

HDP 2.5 will contain Hadoop 2.7.3 not 2.8, if you need to apply patch, please involve Hortonworks support. If you are a customer, HWX can release a patch for you if it's technically possible based on specifics of the JIRAs. If you don't have support, you can certainly do it but test it first. All that said, I would check release notes for HDP 2.5, we may be back porting some 2.8 JIRAs to 2.7.x branch.
