Evgeny Veretennikov created KAFKA-5507:
------------------------------------------
Summary: kafka-run-class.sh doesn't check for empty $CLASSPATH
Key: KAFKA-5507
URL: https://issues.apache.org/jira/browse/KAFKA-5507
Project: Kafka
Issue Type: Bug
Components: tools
Affects Versions: 0.10.2.1
Environment: Linux
Reporter: Evgeny Veretennikov
Assignee: Evgeny Veretennikov
Priority: Minor
Steps to reproduce problem:
1. Clone Kafka repo using {{git clone}}.
2. Run some Bash-script, which invokes {{kafka-run-class.sh}} (without building
project beforehand).
For example:
{{$ ./bin/zookeeper-server-start.sh config/zookeeper.properties
Error: Could not find or load main class config.zookeeper.properties}}
Error is misleading. This happens, because {{kafka-run-class.sh}} tries to run
this command:
{{java ...a lot of JVM options... -cp
org.apache.zookeeper.server.quorum.QuorumPeerMain config/zookeeper.properties}}
Script doesn't check for empty $CLASSPATH variable. It's empty, because we
didn't build project.
{{kafka-run-class.bat}} script for Windows checks for it:
{{IF ["%CLASSPATH%"] EQU [""] (
echo Classpath is empty. Please build the project first e.g. by running
'gradlew jarAll'
EXIT /B 2
)}}
I think, we should add similar check to Bash-script, and show similar error.
