--------------------------------------
Summary: CLASSPATH with single component containing globs breaks
kafka-run-class.sh
Key: KAFKA-7839
URL: https://issues.apache.org/jira/browse/KAFKA-7839
Project: Kafka
Issue Type: Bug
Components: core
Affects Versions: 0.11.0.3
Reporter: Robert Wunderer
Fix For: 0.11.0.3
This issue is very similar to KAFKA-3692, but occurs further down in
kafa-run-class.sh:
If at the end of all processing CLASSPATH contains only a single component
including wildcards, the shell will evaluate CLASSPATH on starting Java, thus
breaking the command line.
To elaborate:
*Problem:*
If CLASSPATH is '/some/path/*', then
{CODE}
java -cp $CLASSPATH
{CODE}
becomes
{CODE}
java -cp /some/path/*
{CODE}
which in turn becomes
{CODE}
java -cp /some/path/file1 /some/path/file2
{CODE}
*Solution:*
This can be prevented by encapsulating CLASSPATH in quotes:
{CODE}
java -cp "$CLASSPATH"
{CODE}
which becomes
{CODE}
java -cp "/some/path/*"
{CODE}
and is handed like that to Java.
