--------------------------------------
Summary: SparkConfigProvider does not handle deprecated config keys
Key: SPARK-22533
URL: https://issues.apache.org/jira/browse/SPARK-22533
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 2.2.0
Reporter: Marcelo Vanzin
Priority: Minor
Noticed that when you read a config using a {{ConfigBuilder}}-created constant
using {{SparkConf.get}}, that does not respect the deprecated keys declared in
{{SparkConf.configsWithAlternatives}}.
For example, adding this test to {{SparkConfSuite}} generates a failure:
{code}
conf.set("spark.history.fs.cleaner.interval.seconds", "42")
assert(conf.get(MAX_LOG_AGE_S) === 42L)
{code}
While here it would also be nice to handle this TODO from
{{SparkConf.configsWithAlternatives}}:
{noformat}
* TODO: consolidate it with `ConfigBuilder.withAlternative`.
{noformat}
