    HDP-2.0 comes bundled with HBase version 0.96.0, and Hadoop version 2.2.0. HDP-1.3 comes bundled with HBase 0.94.6.1 and Hadoop-1.2. These combinations has been tested extensively and supported by HDP. Although not supported by HDP, it should still be possible to use HBase-0.94 series with Hadoop-2, but since HBase build for Hadoop1 and hadoop2 are not binary compatible, you should get the version of HBase build for Hadoop-2.2. Apache Hbase releases does not bundle the binaries for HBase-0.94 build with hadoop-2, so you might need to compile it yourself.

    You can take a look at this: http://hbase.apache.org/book/configuration.html#hadoop to see the support matrix for the apache context.
