    +<dt>\<tablename\> </dt>
    +<dd>The HAWQ table that will store the data to be registered. If the --config option

preferred. If hash distribution must be used, make sure that the distribution policy for the
data files described in the YAML file is consistent with the table being registered into.</dd>

    +<dt>-e , -\\\-eof \<eof\></dt>
    +<dd>Specify the end of the file to be registered. \<eof\> represents the
valid content length of the file, in bytes to be used, a value between 0 the actual size of
the file. If this option is not included, the actual file size, or size of files within a
folder, is used. Used with Use Model 1.</dd>
    +<dt>-F , -\\\-force</dt>
    +<dd>Used for disaster recovery of a cluster. Clears all HDFS-related catalog contents
in `pg_aoseg.pg_paqseg_$relid `and re-registers files to a specified table. The HDFS files
are not removed or modified. To use this option for recovery, data is assumed to be periodically
imported to the cluster to be recovered. Used with Use Model 2.</dd>
    +<dt>-c , -\\\-config \<yml_config\> </dt> 
    +<dd>Registers files specified by YAML-format configuration files into HAWQ. Used
with Use Model 2.</dd>
