[jira] [Commented] (SPARK-15377) Enabling SASL Spark 1.6.1

["Shridhar Ramachandran (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-15377?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15634088#comment-15634088 ] 

Shridhar Ramachandran commented on SPARK-15377:
-----------------------------------------------

It is likely that you haven't enabled spark.authenticate=true in YARN. Excerpted from YarnShuffleService.java --
{noformat}
 * The service also optionally supports authentication. This ensures that executors from one
 * application cannot read the shuffle files written by those from another. This feature can be
 * enabled by setting `spark.authenticate` in the Yarn configuration before starting the NM.
 * Note that the Spark application must also set `spark.authenticate` manually and, unlike in
 * the case of the service port, will not inherit this setting from the Yarn configuration. This
 * is because an application running on the same Yarn cluster may choose to not use the external
 * shuffle service, in which case its setting of `spark.authenticate` should be independent of
 * the service's.
{noformat}
 You can do this by adding that flag to core-site.xml

> Hi there,
> I wonder if anyone gotten SASL to work with Spark 1.6.1 on YARN?
> At this point in time, I cant confirm if this is a bug or not, but, it's definitely reproducible.
> Basically Spark documentation states that you only require 3 parameters enabled:
> spark.authenticate.enableSaslEncryption=true    
> spark.network.sasl.serverAlwaysEncrypt=true
> spark.authenticate=true
> http://spark.apache.org/docs/latest/security.html
> However, upon launching my spark job with --master yarn and --deploy-mode client, I see the following in my spark executors logs:
> 6/05/17 06:50:51 ERROR client.TransportClientFactory: Exception while bootstrapping client after 29 ms
> java.lang.RuntimeException: java.lang.IllegalArgumentException: Unknown message type: -22
