Subject Re: [DISCUSSION] Dropping support for Hadoop 1.0 in 0.98
Date Fri, 31 Oct 2014 22:48:56 GMT
Based on the positive responses thus far, and unless we see an objection
between now and then, I plan to resolve HBASE-12397 next week by removing
support in 0.98 branch for Hadoop 1.0 (but not Hadoop 1.1) in time for
release 0.98.8.
