Re: System memory 186646528 must be at least 4.718592E8.
Thank you . Looking at the source code helped :)
I set spark.testing.memory to 512 MB and it worked :)
private def getMaxMemory(conf: SparkConf): Long = {
val systemMemory = conf.getLong("spark.testing.memory",
Runtime.getRuntime.maxMemory)
val reservedMemory = conf.getLong("spark.testing.reservedMemory",
if (conf.contains("spark.testing")) 0 else RESERVED_SYSTEM_MEMORY_BYTES)
val minSystemMemory = reservedMemory * 1.5
if (systemMemory < minSystemMemory) {
throw new IllegalArgumentException(s"System memory $systemMemory must " +

Here is related code:
val executorMemory = conf.*getSizeAsBytes*("spark.executor.memory")
if (executorMemory < minSystemMemory) {
throw new IllegalArgumentException(s"Executor memory
$executorMemory must be at least " +
