------------------------------
Summary: Log should check the return value of dir.mkdirs()
Key: KAFKA-3940
URL: https://issues.apache.org/jira/browse/KAFKA-3940
Project: Kafka
Issue Type: Bug
Components: log
Affects Versions: 0.10.0.0
Reporter: Jun Rao
In Log.loadSegments(), we call dir.mkdirs() w/o checking the return value and
just assume the directory will exist after the call. However, if the directory
can't be created (e.g. due to no space), we will hit NullPointerException in
the next statement, which will be confusing.
for(file <- dir.listFiles if file.isFile) {
