Application/Operator source and target version may be set to 1.8 as long
as JRE 1.8 is used both on the client and Hadoop cluster. This will
allow to use language constructs introduced in 1.8.

Source level can be 1.8, which allows you to use 1.8 features. Did
you keep target level at 1.7?

I think the problem is what people expect when we say
"certified". To me, If I see something is certified with java
8, I would assume that I can use java 8 api(new features
stream, lambda etc.) to write the operator code, not only just
run the code with jre 8 or compile existing code with jdk 8
and run.
I did try some operator code with java 8 stream API and some
lambda expression in some methods it works. I havn't tried any
operators with new features in their non-transient properties.
And also we should take a look to see if kryo fully works with
java 8 classes/types

You can use Java 8 but the source and target compatibility

your pom.xml for the maven-compiler-plugin still need to

So is it safe to say that JDK 1.8 is supported to the
same extent that 1.7 is?
We’re not running into any issues currently (that I
know of…feel free to chime back in Alex) but we’re
making design decision and were curious about being
able to use Java 8 features.
Thanks!

We do test on Java 8 - both Apex Core and Malhar
Apache Jenkins builds use JDK 1.8 to run tests.
Thank you,

Apex is built against Java 7 and expected to work
as is on Java 8 (Hadoop distros still support 1.7
as well). Are you running into specific issues?

Hey All,
I know there were talks about this at some
point but is Apex and/or Malhar Java 8
certified? If not, is there a current plan and
date to be so?
Thanks,
Alex
