Github user 1ambda commented on the issue:
https://github.com/apache/zeppelin/pull/1638
Currently all interpreters in each group shares same dependencies and
options. So if we create 2 interpreters `postgres1` `postgres2` and set a
dependency `postgres94.client.jar` `postgres95.client.jar` seperately then they
have same 2 dependencies. (**bug**)
I fixed this issue but this results in a lot of copying dependencies in CI
test. So it eventually failed while throwing this message

The log length has exceeded the limit of 4 MB (this usually means that the
test suite is raising the same exception over and over).
The job has been terminated
```
Test was passing but finally failed because of the log size. Could anyone
receommend an idea to resolve this? (I think Travis CI will not increase log
size https://github.com/travis-ci/travis-ci/issues/1382)
