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

             Summary: Some scala codes doesn't show friendly and some description about foreachBatch is misleading
                 Key: SPARK-26791
                 URL: https://issues.apache.org/jira/browse/SPARK-26791
             Project: Spark
          Issue Type: Documentation
          Components: Documentation
    Affects Versions: 2.4.0
         Environment: NA
            Reporter: chaiyongqiang


[Introduction about foreachbatch|http://spark.apache.org/docs/2.4.0/structured-streaming-programming-guide.html#foreachbatch]

[Introduction about policy-for-handling-multiple-watermarks|http://spark.apache.org/docs/2.4.0/structured-streaming-programming-guide.html#policy-for-handling-multiple-watermarks]

The introduction about foreachBatch and policy-for-handling-multiple-watermarks doesn't look good with the scala code.

Besides, when taking about foreachBatch using the uncache api which doesn't exists, it may be misleading.
