[jira] [Updated] (SPARK-8368) ClassNotFoundException in closure for
map
[ https://issues.apache.org/jira/browse/SPARK-8368?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
CHEN Zhiwei updated SPARK-8368:
-------------------------------
Description:
After upgraded the cluster from spark 1.3.0 to 1.4.0(rc4), I encountered the following exception:

```
object Model extends Serializable{
def main(args: Array[String]) {
val Array(sql/*,usePartition,numClasses_, numTrees_,impurity_, maxDepth_, maxBins_*/) = args
val sparkConf = new SparkConf().setAppName("Mode Example")
val sc = new SparkContext(sparkConf)
val hive = new HiveContext(sc)
//get data by hive sql
val rows = hive.sql(sql)
val data = rows.map(r => {
val arr = r.toSeq.toArray
val label = 1.0 //string2Int(arr(r.length-1).toString).toDouble
def fmap = (input: Any) => 1.0 //string2Int(input.toString).toDouble
val feature = arr.map(_=>1.0)
LabeledPoint(label, Vectors.dense(feature))
})
data.count()
}
}
```
=====end code===========
This code can run pretty well on spark-shell, but error when submit it to spark cluster (standalone or local mode). I try the same code on spark 1.3.0(local mode), and no exception is encountered.
