Subject [jira] [Created] (SPARK-5082) Minor typo in the Tuning Spark document about Data Serialization
Date Mon, 05 Jan 2015 02:52:35 GMT
yangping wu created SPARK-5082:
----------------------------------

             Summary: Minor typo in the Tuning Spark document about Data Serialization
                 Key: SPARK-5082
                 URL: https://issues.apache.org/jira/browse/SPARK-5082
             Project: Spark
          Issue Type: Bug
          Components: Documentation
    Affects Versions: 1.2.0
            Reporter: yangping wu
            Priority: Trivial


The latest documentation for *Tuning Spark* has some error entry(http://spark.apache.org/docs/latest/tuning.html)
in the *Data Serialization*: section:
{code}
val conf = new SparkConf().setMaster(...).setAppName(...)
conf.registerKryoClasses(Seq(classOf[MyClass1], classOf[MyClass2]))
val sc = new SparkContext(conf)
{code}
the *registerKryoClasses* method's parameter type should be *Array[Class[_]]* not *Seq[Class[_]]*.
The right code snippets is
{code}
val conf = new SparkConf().setMaster(...).setAppName(...)
conf.registerKryoClasses(Array(classOf[MyClass1], classOf[MyClass2]))
val sc = new SparkContext(conf)
{code}
