Subject Re: Hbase first run problem
Date Wed, 11 Feb 2009 18:13:47 GMT
Yes. In fact, its probably safe-to-do now we've left far behind the
pre-history versions of hbase where there was no hbase.version file in the
hbase.rootdir.  If absent, lets proceed and just write it rather than treat
it as a non-migrated instance.  Want to open an issue jd?
