Leif Wickland created HDFS-5387:
-----------------------------------
Summary: Documentation on FileSystem.createNewFile() is misleading
Key: HDFS-5387
URL: https://issues.apache.org/jira/browse/HDFS-5387
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Leif Wickland
Priority: Trivial
Attachments: FileSystem.java.patch
The documentation for FileSystem.createNewFile() indicates that it will return
false if it failed to create the requested file. In fact, it will only return
false if the file existed before the function was called. Also the function
fails to mention that a race condition can result in an exception be thrown if
another process attempts to create the file at the same time.
