------------------------------------
Summary: Error uploading JAR with dependencies using flink.bat on
a Windows stand-alone instance
Key: FLINK-4058
URL: https://issues.apache.org/jira/browse/FLINK-4058
Project: Flink
Issue Type: Bug
Reporter: Mark Nadelson
Priority: Critical
Uploading a JAR with dependencies in a sub-directory causes an" Unable to
create temporary file" IOException. This occurs in
org.apache.flink.client.program.PackagedProgram.extractContainedLibraries()
This because of the line "name = name.replace(File.separatorChar, '_');"
File.separatorChar in windows is the backslash (\) but files read from a Jar
are always in the format of the forward slash (/). Therefore the slash is
never replaced with the '_'. The fix is to remove the File.separatorChar with
'/'.
