Kun Liu updated TOREE-395:
--------------------------
Description:
Scala REPL supports a flag, ":silent" to enable/disable automatic printing of
results (those messages begin with "res"). 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:
