      Trunk no longer has support for hadoop1. You cannot build against hadoop1. We now generate one artifact only and our artifact naming no longer includes the hadoop version we were built against since we only build against one version, hadoop2: e.g. the hbase 1.0.0 release will be named hbase-1.0.0, not hbase-1.0.0-hadoop1 (or hbase-1.0.0-hadoop2).

      Description

      As per thread:
      http://mail-archives.apache.org/mod_mbox/hbase-dev/201403.mbox/%3CCAMUu0w93MGp7ZBbxGccOV+be3EtMkvn5ATZOwvzQD_gegdK4NQ@mail.gmail.com%3E

      It seems that the consensus is that supporting Hadoop-1 in HBase-1.x will be costly, so we should drop the support.

      In this issue:

      • We'll document that Hadoop-1 support is deprecated in HBase-0.98. And users should switch to hadoop-2.2+ anyway.
      • Document that upcoming HBase-0.99 and HBase-1.0 releases will not have Hadoop-1 support.
      • Document that there is no rolling upgrade support for going between Hadoop-1 and Hadoop-2 (using HBase-0.96 or 0.98).
      • Release artifacts won't contain HBase build with Hadoop-1.
      • We may keep the profile, jenkins job etc if we want.
