fix the issue: The hdfs connector cannot read correctly from the hfds files which generated by the hdfs connector itself.
When hdfs connector writing data to hdfs, null value of a column is set as a member of a String array that is a data row`s output, eg, data[0] = null, that results in "null" string value would be written into the hdfs text files.
solution:
null value is set to '\N' for hive specification so that hdfs connector can read from the output.
