To elaborate my question,
Reference -
During the first virtual index search, Hunk copies this package to HDFS then extracts it into all TaskTracker nodes that participate in the search. The extracted package is used to process search results in Hadoop.
No, Hunk does not need to be installed on any of the Hadoop nodes. It only needs to be installed as a Hunk search head, as it sounds like you've done. Any copying of the splunkd executable or package will be done automatically by the Hunk search head as needed.
The reference you've copied refers to what happens internally when you run a virtual index search on Hunk search head.
