Spark-submit 提交任务时候报错

Exception in thread "main" java.lang.IllegalArgumentException: System memory 202768384 must be at least 4.718592E8. Please use a larger heap size.

/usr/local/app/spark-1.6.1/bin/spark-submit
--class cn.tbnb1.spark.sql.DataFrameCreate
--master spark://v1:7077
--num-executors 2
--driver-memory 100m
--executor-memory 100m
--executor-cores 2

/usr/local/testdata/spark-data/java/sql/jar/spark-demoes.jar

这是脚本

分析了下 ，我先是加大了虚拟机内存。 但是问题还是没解决。

看来是driver内存不足，当给了 driver的内存尝试着增大到400M 时候

仍旧是爆出如下错

Exception in thread "main" java.lang.IllegalArgumentException: System memory 402128896 must be at least 4.718592E8. Please use a larger heap size.

此时就可以再次调大一些 给了1g（应该是从spark升级1.5或者1.6之后才出现这样的问题，）

然后再次运行之后正常得出结果

还可以指定在代码中 ：

 val conf = new SparkConf().setAppName("word count")
 conf.set("spark.testing.memory", "1g")//后面的值大于512m即可

解决问了，
