Hi,

I've had the opportunity to talk about HBCK2 with a few of you. One of the
suggestions is to to have a separate git repository for HBCK2. Lets discuss
about it.

In the past when bugs were found in hbck, there is no easy way to release
patched version of just hbck (without patching HBase). If HBCK2 has a
separate git repo, HBCK2 versions will not be tightly related to HBase
versions. Fixing and releasing hbck2, may not require patching HBase.
Though tight coupling will be somewhat loosened, HBCK2 will still depend on
HBase APIs/ code. Caution will be required going forward regarding
compatibility.

What you all think?

Thanks,
Umesh
