Nitzan Niv created KAFKA-6162:
---------------------------------
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:
