Wing Yew Poon created SPARK-5485:
------------------------------------

             Summary: typo in spark streaming configuration parameter
                 Key: SPARK-5485
                 URL: https://issues.apache.org/jira/browse/SPARK-5485
             Project: Spark
          Issue Type: Bug
          Components: Documentation
    Affects Versions: 1.2.0
            Reporter: Wing Yew Poon


In https://spark.apache.org/docs/1.2.0/streaming-programming-guide.html#deploying-applications, under "Requirements", the bullet point on "Configuring write ahead logs" says

"This can be enabled by setting the configuration parameter spark.streaming.receiver.writeAheadLogs.enable to true."

There is an unfortunate typo in the name of the parameter, which I copied-and-pasted into my deployment where I was testing it out and seeing data loss as a result. 
The same typo occurs in https://spark.apache.org/docs/1.2.0/configuration.html, which is even more unfortunate.
Documentation should not have typos like this for configuration parameters. I later found the correct parameter on http://databricks.com/blog/2015/01/15/improved-driver-fault-tolerance-and-zero-data-loss-in-spark-streaming.html.
