Ismael Juma reassigned KAFKA-6855:
----------------------------------
Assignee: Ismael Juma
> Kafka fails to start due to faulty Java version detection
> ---------------------------------------------------------
>
> Key: KAFKA-6855
> URL: https://issues.apache.org/jira/browse/KAFKA-6855
> Project: Kafka
> Issue Type: Bug
> Components: core
> Affects Versions: 1.1.0
> Environment: Ubuntu 18.04
> Java 10
> Reporter: Anders Tornblad
> Assignee: Ismael Juma
> Priority: Major
>
> After downloading fresh installations of ZooKeeper and Kafka, and then
> starting ZooKeeper and Kafka the way that is recommended on
> [http://kafka.apache.org/documentation/#quickstart] the following error
> message is shown:
> {{Unrecognized VM option 'PrintGCDateStamps'}}
> I found the error in the kafka-run-class.sh file, where the Java version is
> determined and put in the JAVA_MAJOR_VERSION variable. My Java runtime
> reports the version as openjdk version "10.0.1" 2018-04-17, which makes the
> JAVA_MAJOR_VERSION value be "10 2018-04-17" instead of just "10". That makes
> the subsequent if statement fail.
> I found the following line to fix the problem:
> {{JAVA_MAJOR_VERSION=$($JAVA -version 2>&1 | sed -E -n 's/.* version
> "([^.-]*).*/\1p')}}
>
