cool elasticsearch client

I was searching for an elastic client so I can have auto-complete for queries and a graphical way of seeing how things are going for our test elastic servers. Few years ago we had Sense plug-in which I think now a part of Kibana. After a little googling, I found head plug-in for chrome and it is so cool. I highly recommend it to everyone with this kind of need.

org.openqa.selenium.WebDriverException: cannot get automation extension

In our current project, we write CI tests using Selenium. But several weeks has passed since I wrote a new test and there goes a nice exception while running the old ones.

  
org.openqa.selenium.WebDriverException: unknown error: cannot get automation extension

Doesn't explain much, right?
I find the solution in upgrading my chrome driver.
