You have been given below directory location (if not available than create it) /tmp/nrtcontent.

As soon as file committed in this directory that needs to be available in hdfs in /tmp/flume location
Data
echo "I am preparing for CCA175 from ABCTECH.com" > /tmp/nrtcontent/.he1.txt mv /tmp/nrtcontent/.he1.txt /tmp/nrtcontent/he1.txt
After few mins
echo "I am preparing for CCA175 from TopTech.com" > /tmp/nrtcontent/.qt1.txt mv /tmp/nrtcontent/.qt1.txt /tmp/nrtcontent/qt1.txt
Write a flume configuration file named flumes.conf and use it to load data in hdfs with following additional properties.
1 . Spool /tmp/nrtcontent
2 . File prefix in hdfs sholuld be events
3 . File suffix should be Jog
4 . If file is not commited and in use than it should have as prefix.
5 . Data should be written as text to hdfs
