[jira] [Created] (SPARK-5774) Support save RDD append to file

Yanbo Liang created SPARK-5774:
----------------------------------

             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
            Reporter: Yanbo Liang


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.
