Description

If running Apache Drill on versions 1.10 / 1.11 on JRE it appears that queries no longer run without JDK, but the /status monitoring API endpoint does not reflect the fact the Apache Drill will not work and still returns 'Running'.

While 'Running' is technically true the process is up, it's effectively broken and Apache Drill should either reflect this in /status that is is broken or refuse to start up on JRE altogether.
