Description

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)
