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}
