Hi Prabhakar,
Rafael has pointed you in the right direction. Drill does code generation at
run time and for that it needs the Java compiler which requires the JDK, not
just the JRE.
I do development on Linux (Ubuntu-based Linux Mint) and was able to install the
JDK. It's been awhile so I don't recall exactly what I did.
Which distro are you using? There are different ways to install the JDK
depending on your distro. I find a Google search often reveals the correct path
for each.
That you have to ask this question shows a hole in the Drill documentation.
Please file a JIRA ticket to describe the problem. Once you find how to install
the JDK on your distro, please add that to the ticket so we can update the docs.
Thanks,
- Paul
