You can assign the issue to me. I have the build environment configured and can successfully run build and basic unit tests.

> While setting MR job configuration HiveColumnCardinalityJob.java uses deprecated parameter name for HDFS block size.
> Since Hadoop 2.5 (at least) recommended parameter name is dfs.blocksize, while the existing code (2.2.0 and earlier) uses dfs.block.size (please refer to the list of Hadoop deprecated parameters - http://hadoop.apache.org/docs/r2.7.3/hadoop-project-dist/hadoop-common/DeprecatedProperties.html)
