----------------------------------
Summary: Add more flexible getAllWithPrefix for SparkConf
Key: SPARK-53980
URL: https://issues.apache.org/jira/browse/SPARK-53980
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 4.1.0
Reporter: Jiaan Geng
Assignee: Jiaan Geng
We need to set some config related to S3 for our inner Spark. The
implementation of the function show below.
{code:java}
private def setS3Configs(conf: SparkConf): Unit = {
val S3A_PREFIX = "spark.fs.s3a"
val SPARK_HADOOP_S3A_PREFIX = "spark.hadoop.fs.s3a"
val s3aConf = conf.getAllWithPrefix(S3A_PREFIX)
s3aConf
.foreach(
confPair => {
val keyWithoutPrefix = confPair._1
val oldKey = S3A_PREFIX + keyWithoutPrefix
val newKey = SPARK_HADOOP_S3A_PREFIX + keyWithoutPrefix
val value = confPair._2
conf.remove(oldKey)
conf.set(newKey, value)
logInfo(s"Migrate $oldKey to $newKey")
})
}
{code}
These code seems redundant and complicated. The reason is getAllWithPrefix only
return the suffix part.
