------------------------------
    Resolution: Duplicate

> 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.
