The Hive table is just a directory in HDFS, so you can recursively set the
replication factor on it as you like. You can set it to the number of datanodes
you have. If you have 100 nodes, then run this after you create your table:
hadoop fs -setrep -R -w 100
/path/to/hive/warehouse/small_table_to_be_distributed
