…n Design Patterns for using foreachRDD ## What changes were proposed in this pull request? Added missing Java example under section "Design Patterns for using foreachRDD". Now this section has examples in all 3 languages, improving consistency of documentation. ## How was this patch tested? Manual. Generated docs using command "SKIP_API=1 jekyll build" and verified generated HTML page manually. The syntax of example has been tested for correctness using sample code on Java1.7 and Spark 2.2.0-SNAPSHOT. Author: adesharatushar <tushar_adeshara@persistent.com> Closes #16408 from adesharatushar/streaming-doc-fix. (cherry picked from commit dba81e1) Signed-off-by: Sean Owen <sowen@cloudera.com>
