Description:

run with no parameters.
{code}
$ hadoop jar /usr/lib/hadoop-mapreduce/hadoop-mapreduce-examples.jar sort
ERROR: Wrong number of parameters: 0 instead of 2.
sort [-m <maps>] [-r <reduces>] [-inFormat <input format class>] [-outFormat
<output format class>] [-outKey <output key class>] [-outValue <output value
class>] [-totalOrder <pcnt> <num samples> <max splits>] <input> <output>
Generic options supported are
-conf <configuration file> specify an application configuration file
-D <property=value> use value for given property
-fs <local|namenode:port> specify a namenode
-jt <local|jobtracker:port> specify a job tracker
-files <comma separated list of files> specify comma separated files to be
copied to the map reduce cluster
-libjars <comma separated list of jars> specify comma separated jar files to
include in the classpath.
-archives <comma separated list of archives> specify comma separated
