--------------------------------------
Summary: SparkConf deprecation log messages are printed multiple
times
Key: SPARK-13626
URL: https://issues.apache.org/jira/browse/SPARK-13626
Project: Spark
Issue Type: Bug
Components: Spark Core, SQL
Affects Versions: 2.0.0
Reporter: Marcelo Vanzin
Priority: Minor
I noticed that if I have a deprecated config in my spark-defaults.conf, I'll
see multiple warnings when running, for example, spark-shell. I collected the
backtrace from when the messages are printed, and here's a few instances. The
first one is the only one I expect to be printed.

java.lang.Exception:

at org.apache.spark.SparkConf.<init>(SparkConf.scala:53)
at org.apache.spark.repl.Main$.<init>(Main.scala:30)
{noformat}
The following ones are causing duplicate log messages and we should clean those
up:

{noformat}
There are also a few more caused by the use of {{SparkConf.clone()}}.
