Subject [jira] [Commented] (SPARK-4739) spark.files.userClassPathFirst does not work in local[*] mode
Date Thu, 22 Jan 2015 19:23:35 GMT


Marcelo Vanzin commented on SPARK-4739:

I'm pretty sure I tested that change in local mode, explicitly overriding a jar that Spark
uses with an incompatible one, and things worked. But I can check again...

> The parameter "spark.files.userClassPathFirst=true" does not work when using spark-submit
with "\-\-master local\[3\]". In particular, even though my application jar file contains
netty-3.9.4.Final, the older version from the spark-assembly jar file is loaded (cf. SPARK-4738).
When using the same jars with "\-\-master yarn-cluster" and "spark.yarn.user.classpath.first=true"
(cf. SPARK-2996), it works correctly and my bundled classes are used.
