Summary: Check if proper JAR file in JobWithJars
Key: FLINK-12631
URL: https://issues.apache.org/jira/browse/FLINK-12631
Project: Flink
Issue Type: Improvement
Reporter: Ji Liu
Assignee: Ji Liu
Currently, _checkJarFile_ checks if the file exists and canRead. Jar file is
checked much later than necessary.
As an intermediate solution we can check if proper jar file right in this
method to early detect illegal problems.
