Drop Java 7 support? (re-open ZEPPELIN-621?)
Hi all
Right now Zeppelin is compiled for Java 7 as minimal version.
But it already EOL for a long time, so it makes sense to stop supporting it.
There are several reasons for it:
- Spark 2.2.0 that is used by Zeppelin (at least in master) supports
only Java 8+
- Switch to Java 8 will allow to write more clear code for Java part of
the Zeppelin code.
This switch was already discussed as
https://issues.apache.org/jira/browse/ZEPPELIN-621, but it was more than 2
years ago.
What do you think?
