-----------------------------------
Summary: SparkLauncher's setConf() does not support configs with
spaces in their typing
Key: SPARK-12176
URL: https://issues.apache.org/jira/browse/SPARK-12176
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 1.5.2, 1.5.1, 1.5.0, 1.4.1, 1.4.0
Environment: All
Reporter: Yuhang Chen
Priority: Minor
The spark-submit uses '--conf K=V' pattern for setting configs. And according
to the docs, if the 'V' you set contains spaces in it, you should wrap the
whole 'K=V' parts with quotes. However, the SparkLauncher
(org.apache.spark.launcher.SparkLauncher) would not wrap the ‘K=V' parts for
you, and there is no place for wrapping by yourself with the API it provides.
I checked up the source, all confs are stored in a Map before generating
launching commands. Thus. my advice is checking all values of the conf Map and
do wrapping during command building.
