Jakob Homan updated SAMZA-202:
------------------------------
Attachment: SAMZA-202-draft.patch
Started on this, but not done yet.
* Switched to Gradle 2, which had a [build error that looks spurious and was
based on an extra
parameter|http://forums.gradle.org/gradle/topics/publishing_task_breaks_from_gradle_1_6_to_2_0_with_task_with_name_not_found?utm_source=notification&utm_medium=email&utm_campaign=new_reply&utm_content=topic_link]
* The Gradle publish task no longer publishes the md5 or sha1 files; this
should probably be handled in another JIRA as it will likely require assistance
from the Gradle guys.
* The license check plugin was using a removed Gradle command. Upgraded to
0.9. This version is better at catching unlicensed files (the css and js
files), but still has no way to whitelist individual files. Since we're going
to RAT, I've just turned on the treat-these-as-warnings flag, which gives us
the same behavior as before.
* Running into a bigger issue with Jetty and Samza YARN. We bring in Jetty 8
for our web servers but YARN uses Jetty 6 (and is pretty stuck on that
version). Java 8 has a problem with the jars between the two as they're signed
differently and fails (at least) testAppMasterDashboardShouldStart (with
"java.lang.SecurityException: class "javax.servlet.HttpConstraintElement"'s
signer information does not match signer information of other classes in the
same package" At least this is my guess based on initial stack overflowing;
this appears to be a common error.
Need to poke a bit more to confirm it's Jetty that's the culprit, but if so,
we'll have a tough time sorting these jars. It will be difficult to sort out
the servlets we run in our AM from the AM/YARN logic itself...
