增加Spark shell可用的内存

Question

我正在尝试在Raspberry Pi1 Model B +上安装Apache Spark

一旦我启动命令shell并尝试命令:

val l = sc.parallelize(List()).collect

我收到例外:

scala> val l = sc.parallelize(List()).collect
15/03/22 19:52:44 INFO SparkContext: Starting job: collect at <console>:21
15/03/22 19:52:44 INFO DAGScheduler: Got job 0 (collect at <console>:21) with 1 output partitions (allowLocal=false)

./spark-shell: line 55:  3596 Segmentation fault      "$FWDIR"/bin/spark-submit --class org.apache.spark.repl.Main "${SUBMISSION_OPTS[@]}" spark-shell "${APPLICATION_OPTS[@]}"

启动命令shell时,我允许磁盘内存利用率:

./spark-shell --conf StorageLevel=MEMORY_AND_DISK

但仍然收到同样的例外.

当启动spark shell时,有267MB可用内存:

15/03/22 17:09:49 INFO MemoryStore: MemoryStore started with capacity 267.3 MB

这应该是足够的内存在shell中运行Spark命令吗？

这是正确的命令启动火花壳,将不可用的内存溢出到磁盘:./spark-shell --conf StorageLevel=MEMORY_AND_DISK？

更新:

我试过了 :

./spark-shell --conf spark.driver.memory=256m

val l = sc.parallelize(List()).collect

但结果相同

Answer 1

尝试--driver-memory选项为驱动程序进程设置内存.例:

./spark-shell --driver-memory 2g

适用于2 GB内存.
