Aaron T. Myers updated HDFS-2983:
---------------------------------
Attachment: HDFS-2983.patch
I realized that the previous patch had a bug in handling numeric groups of
characters after non-numeric groups in version components. Here's an updated
patch with added test cases to cover this case.
> Relax the build version check to permit rolling upgrades within a release

> 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.
