This is also supported in Spark > shell. But for Toree Scala kernel, this flag is not supported. Thus the > result of a cell would be always printed. > But if there is any logging mechanism, the results would be recorded in a log > file, while this may not be desirable. For instance, a user may not want any > sensitive data logged when running "dataRDD.take(5)" in a cell. > Also found the possible source codes for this: > https://github.com/apache/incubator-toree/blob/master/scala-interpreter/src/main/scala/org/apache/toree/kernel/interpreter/scala/ScalaInterpreter.scala > There are three methods with silent: Boolean = false as parameter. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
