--------------------------------

             Summary: clean up the implementation of `growToSize` in CompactBuffer
                 Key: SPARK-22254
                 URL: https://issues.apache.org/jira/browse/SPARK-22254
             Project: Spark
          Issue Type: Bug
          Components: Spark Core
    Affects Versions: 2.2.1
            Reporter: Feng Liu


two issues:

1. the arrayMax should be `ByteArrayMethods.MAX_ROUNDED_ARRAY_LENGTH `
2. I believe some `-2` were introduced because `Integer.Max_Value` was used previously. We should make the calculation of newArrayLen concise.
