Hive Service Upgrade from 1.x to 2.x

[#1]

Id like to know if only hive service can be upgraded in CDH 5.4.x cluster.

I have an parcel installation.

@TheDarkWizard,

Short answer: No.

When using parcels, all components are upgraded at the same time as all of CDH ships in one parcel.  We test these parcels to promote stability and reliability, so I would recommend going forward witn an upgrade.  We will not be providing fixes for 5.4.x any longer, so it would be good to consider upgrading to our latest releases.
