Create a sample test.txt file:

foo
bar
foo
bar
foo

Log in as the $HDFS_USER. The $HDFS_USER is the user that owns the HDFS service. For example, hdfs:

su $HDFS_USER

Create a /tmp/input/ directory in HDFS and copy the test.txt file into that directory:

hdfs dfs -mkdir -p /tmp/input/
hdfs dfs -put test.txt /tmp/input/

Execute the following command to run the OrderedWordCount application using Tez:

hadoop jar /usr/hdp/current/tez-client/tez-examples-*.jar orderedwordcount /tmp/input/test.txt /tmp/out

Run the following command to verify the word count:

hdfs dfs -cat '/tmp/out/*'

This should return:

foo 3
bar 2
