This commit fixes issue CDH-18969 where Impala returns wrong results when querying an HBase table. This issue is triggered when a column family sorts lexicographically before ":key", which is the column family of the row key, thereby causing the wrong column to be used as a row key by the backend. The following changes are included: 1. Modified the load function in HBaseTable.java to make sure the catalog object of an HBase table always stores the row key column first.
