Apache drill – No current connection
After reading multiple posts, it seems that this is a problem of conflicting jars.
My current setup has apache drill installed using $brew install apache-drill and upon executing $drill-embedded or $drill-localhost, I see below error (line 10)

It works fine upon launching clean shell. Below is the modified command to launch drill-embedded
env -i HOME="$HOME" LC_CTYPE="${LC_ALL:-${LC_CTYPE:-$LANG}}" PATH="$PATH" USER="$USER" drill-embedded
See how well it behaved for me 😉
robin@MacBook-Pro:~$ env -i HOME="$HOME" LC_CTYPE="${LC_ALL:-${LC_CTYPE:-$LANG}}" PATH="$PATH" USER="$USER" drill-embedded

Ended up creating this alias for my bash profile
alias drill="env -i HOME="$HOME" LC_CTYPE="${LC_ALL:-${LC_CTYPE:-$LANG}}" PATH="$PATH" USER="$USER" drill-embedded"
