https://github.com/apache/zeppelin/pull/1538
@astroshim sorry for the belated response. I worked on fixing the issue of
zeppelin version 0.6.It's solved by installing scala on the docker. This issue
only happens with the binary version downloaded from zeppelin website, but when
creating an image from create_release.sh script, it worked normally without
scala installation requirement.
The logs of the issue:
