KafkaSource.java:[468,37] error: cannot find symbol [ERROR] variable
zkUtils of type ZkUtils
Hi to everyone!
I am trying to compile flume with latest kafka 0.11.0.1 and got the
following
[ERROR] Failed to execute goal
org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile
(default-compile) on project flume-kafka-source: Compilation failure:

That is strange trouble because we have that class in imports. That looks
for me like environment trouble (Maven version maybe). Does someone compile
flume with kafka 0.11.0.1?

Oh!
I should learn Scala. I never suspect such changes in minor version. Thanks
for help. I made patch based on your and attach that here. Should I do
something more? Create ticket in Jira maybe?

Hi Anton,
with the kafka upgrade, there comes a scala-library update as well and for
the 2.11 scala version there were backward compatibility breaking changes
in this case scala.collection.JavaConverters.asJavaListConverter has been
removed
I have attached part of my solution of this upgrade.
You may not be able to apply the diff file itself, but the solution is in
it.
Let me know if you need more help with it.
