Review comment:
The official Ubuntu phantomjs has a caveat: it requires X Window. (ariya/phantomjs#14376 (comment)). Add environment var QT_QPA_PLATFORM=offscreen to make it really 'headless". If it's not headless, the installer fails to execute phantomjs and abort.

Review comment:
We need python2.7 package, because hadoop-yarn-project/hadoop-yarn/hadoop-yarn-ui installs node-gyp 3.8, which has dependency on python2 to build.
