Summary: Support save RDD append to file
Key: SPARK-5774
URL: https://issues.apache.org/jira/browse/SPARK-5774
Project: Spark
Issue Type: New Feature
Components: Spark Core
Affects Versions: 1.3.0

Now RDD.saveAsTextFile only support writing to a file which is empty. In some
cases, we need to save RDD append to an existing file. For example, when
execute SQL command "INSERT INTO ...", we need to append the RDD to an existing
file.
