(Belated) All HSM related work has been backported into branch-1 through HBASE-19858, but not released yet (should be included in 1.5.0).
Notice that the current commit breaks compatibility with hadoop 2.4/2.5 (the reason that the jira is reopened), so if you are on hadoop 2.6+ and need HSM support, just cherry-pick the HBASE-19858 commit from branch-1 and try it in your own version. Hope this information helps.
