spark编译 ./sbt/sbt assembly Error occurred during initialization of VM

最近在学spark，尝试自己编译，在一台VM上遇到了:

[root@localhost spark-1.1.0]# ./sbt/sbt  assembly
Error occurred during initialization of VM
Could not reserve enough space for object heap
Could not create the Java virtual machine.

解决方法：

./sbt/sbt -mem512 assembly

问题解决。
