I installed apache-spark 1.6.1 lately and then I uninstalled it and update homebrew to install apache-spark 2.0.0. However, When I run
brew doctor I don't get any helpful diagnostics about what is wrong:
Error: No such file or directory - /usr/local/Cellar/apache-spark/1.6.1
What should I do now? The version of my os is 10.11.6.
