Hi please can someone let me know what are are core jar files and
depeancies we need to attach in classpath for a job to compile successfully

If you are compiling in the old-world way (javac!) it would be simpler
to use the whole classpath, given the modularity of jars, such as:
$ javac -cp `hadoop classpath` -d wordcount_classes WordCount.java
Where the command `hadoop classpath` in the shell automatically
expands and provides a usable classpath.
If you want a better approach, I highly recommend using Apache Maven
or similar tools with the hadoop-client dependency added instead.
