Description

As of 01/04/2016, the following tests fail in the MiniTezCliDriver mode when the cbo return path is enabled. We need to fix them :

 vector_leftsemi_mapjoin
 vector_join_filters
 vector_interval_mapjoin
 vector_left_outer_join
 vectorized_mapjoin
 vector_inner_join
 vectorized_context
 tez_vector_dynpart_hashjoin_1
 count
 auto_sortmerge_join_6
 skewjoin
 vector_auto_smb_mapjoin_14
 auto_join_filters
 vector_outer_join0
 vector_outer_join1
 vector_outer_join2
 vector_outer_join3
 vector_outer_join4
 vector_outer_join5
 hybridgrace_hashjoin_1
 vector_mapjoin_reduce
 vectorized_nested_mapjoin
 vector_left_outer_join2
 vector_char_mapjoin1
 vector_decimal_mapjoin
 vectorized_dynamic_partition_pruning
 vector_varchar_mapjoin1

This jira is intended to cover the vectorization issues related to the MiniTezCliDriver failures caused by NPE via nullSafes array as shown below :

private boolean onExpressionHasNullSafes(MapJoinDesc desc) {
     boolean[] nullSafes = desc.getNullSafes();
     for (boolean nullSafe : nullSafes) {
