added log info for clarity while running the test with additional params- test huge field

[rashmivkulkarni]

Adding additional log.info - in case the test fails and has instructions how to run this test with additional params while starting the test.

investigating -- if there is another better way if we can decrease the number of fields or make a change where it's still within the default bounds. Or, can we post to ES directly.

jenkins, test this
