Hi,
I have a problem going through start guide on Windows. Basically what I
found are file path problems it seems:
If I try to set Kafka log dir path in server.properties using Windows file
separator, such as
D:\tmp\kafka-logs, or even
\tmp\kafka-logs
, then kafka cannot be started, since it throws
[2014-01-25 08:04:00,495] FATAL Fatal error during KafkaServerStable
startup. Prepare to shutdown (kafka.server.KafkaServerStartable)
java.io.IOException: The filename, directory name, or volume label syntax is
incorrect

If I use Unix file separator in settings, such as default /tmp/kafka-logs,
(and for those who don't use Windows, java on Windows accepts paths that
have unix path separator such as D:/tmp/some.file), then Kafka can be
started, but during topic creation I get following error which I assume is
due to trying to find the key using windows file separator as given in
exception log:
