# ====== leaving this in, in case someone can get it to work on mavericks
|

#
|
||||
# A REALLY bad test... however Kafka doesn't say its version anywhere so its the best we can do.
|
||||
# Furthermore, we can't just start and stop a ZK and Kafka instance, as theyd need to daemonize, and
|
||||
# in order to daemonize, they need to write access to a place where they expect to put their PID file
|
||||
# but that's impossible inside the sandbox.
|
||||
#
|
||||
# The ZooKeeper client that Kafka uses spits out some key JVM parameters when it is first initialized,
|
||||
# namely "java.class.path", which gets set by kafka-run-class.sh, which is called by kafka-server-start.sh
|
||||
# Thus, a correct java.class.path implies that the correct version of Kafka has been installed and is running when
|
||||
# the command to start are invoked and the fact that it runs to begin with indicates that the
|
||||
# prerequisites for successful environment to run in are met.
|
||||
#
|
||||
# We simply check that the classpath has the JAR of the Kafka version we want to use. But first, we need to
|
||||
# set a few environment variables that kafka-run-class.sh uses for things like figuring out where
|
||||
# to save logs. We need to do this so that Kafka doesnt try to write log files into
|
||||
# /usr/local/Cellar/kafka/version/blahblah and instead into the sandbox's temporary directory, because otherwise
|
||||
# instead of lovely ZooKeeper client debug messages, we just get a bunch of "operation not permitted" IO errors
|
||||
# and Kafka will crash (or worse, livelock) before the ZK client has a chance to start and work its magic.
