    +DESCRIPTION
    +*****************************************************
    +
    +"hawq register" is a utility to register file(s) on HDFS into
    +the table in HAWQ. It moves the file in the path(if path
    +refers to a file) or files under the path(if path refers to a
    +directory) into the table directory corresponding to the table,
    +and then update the table meta data to include the files.
    +
    +To use "hawq register", HAWQ must have been started.
    +
    +Currently "hawq register" supports parquet tables only.
    +User have to make sure that the meta data of the parquet file(s)
    +and the table are consistent.
    +The table to be registered into should not be hash distributed, which
    +is created by using "distributed by" statement when creating that table.
    +
