The way you suggested can pass as well. After further investigating, I
found
[```install.spark()```](https://github.com/apache/spark/blob/master/R/pkg/tests/run-all.R#L25)
is the root cause that makes my test fail. But I still not figure out which
line in that function caused the failure.
I change the test case to a more simple way, which can still verify the
fix. Without this fix, the updated test will fail. Since Spark 2.2 is coming
and this fix passed for sparkR shell test and yarn cluster mode test, we can
get this in firstly, and leave a todo for that weird test failure.
