---------------------------------

             Summary: Stream Store tries to create directory with invalid name on Windows
                 Key: KAFKA-6162
                 URL: https://issues.apache.org/jira/browse/KAFKA-6162
             Project: Kafka
          Issue Type: Bug
          Components: streams
    Affects Versions: 1.0.0
         Environment: Windows
            Reporter: Nitzan Niv
            Priority: Major


Stream store attempts to create a file with name generated from segment ID:
Segments.java, line 72: name + ":" + segmentId * segmentInterval

":" is invalid in directory name on Windows, so directory creation fails in RocksDB, with following exception:
