Hi Prabhakar,
As it turns out, Drill is built for Java 8-13, but we've not built for Java 7
in quite some time. (Java 7 reached end of life several years back.)
That said, you can try to clone the project sources and do a build.
Unfortunately, the JDBC driver tends to use quite a bit of Drill's internals
and so has a rather large footprint, some of which is likely to depend on Java
8.
Further, Drill depends on a large number of libraries, all of which have likely
been upgraded to Java 8. You'd have to find old Java 7 versions, and then
figure out how to change Drill code to work with those old versions.
One might well ask, is it possible for you to upgrade to a supported Java
version? Drill must not be the only library where you have the Java 8
dependency problem.
Thanks,
- Paul

Hi All,
We are using drill 1.16.0 and we are trying to create JDBC datasource on
WAS8.5 with java7. we are getting following error.
"exception: java.sql.SQLException: java.lang.UnsupportedClassVersionError:
JVMCFRE003 bad major version; class=org/apache/drill/jdbc/Driver, offset=6"
So where can i get the JDBC driver compiled for java7? thx
