      Description

      Currently the version check for DN/NN communication is strict (it checks the exact svn revision or git hash, Storage#getBuildVersion calls VersionInfo#getRevision), which prevents rolling upgrades across any releases. Once we have the PB-base RPC in place (coming soon to branch-23) we'll have the necessary pieces in place to loosen this restriction, though perhaps it takes another 23 minor release or so before we're ready to commit to making the minor versions compatible.
