It is streaming the output from HDFS to HDFS:</P><P>============================</P><P>A command line scriptlet to do this could be as follows:</P><PRE>hadoop fs -text *_fileName.txt | hadoop fs -put - targetFilename.txt </PRE><P>This will cat all files that match the glob to standard output, then you'll pipe that stream to the put command and output the stream to an HDFS file named targetFilename.txt</P><P>=============================</P> Tue, 10 Oct 2017 02:58:12 GMT manish1 2017-10-10T02:58:12Z
