leesf created FLINK-12148:
-----------------------------
Summary: Give precedence to specified local jar when same
mainClass is included in both lib and specified jar
Key: FLINK-12148
URL: https://issues.apache.org/jira/browse/FLINK-12148
Project: Flink
Issue Type: Bug
Components: Command Line Client
Affects Versions: 1.8.0
Reporter: leesf
Assignee: leesf
Fix For: 1.9.0
When submitting the flink job with ./flink run -c mainClass localJar. If the
main class is included in the $FLINK_HOME/lib directory and the specified jar
package, then the mainClass in the $FLINK_HOME/lib directory is executed
instead of the specified localJar.
For example, There is flink-examples-streaming_2.11-1.9-SNAPSHOT.jar in lib
directory that contains the
org.apache.flink.streaming.examples.wordcount.WordCount class, and
LocalWordCount.jar also contains org.apache.flink.streaming.examples.wordcount
The .WordCount class, then use ./flink run -c
org.apache.flink.streaming.examples.wordcount.WordCount /tmp/LocalWordCount.jar
to submit job, the WordCount class in
flink-examples-streaming_2.11-1.9-SNAPSHOT.jar is executed in instead of
LocalWordCount.jar.
