Sanket Reddy created SPARK-21798:
------------------------------------
Summary: No config to replace deprecated SPARK_CLASSPATH config
for launching daemons like History Server
Key: SPARK-21798
URL: https://issues.apache.org/jira/browse/SPARK-21798
Project: Spark
Issue Type: Bug
Components: Spark Core
Affects Versions: 2.2.0
Reporter: Sanket Reddy
Priority: Minor
History Server Launch uses SparkClassCommandBuilder for launching the server.
It is observed that SPARK_CLASSPATH has been removed and deprecated. For
spark-submit this takes a different route and spark.driver.extraClasspath takes
care of specifying additional jars in the classpath that were previously
specified in the SPARK_CLASSPATH. Right now the only way specify the additional
jars for launching daemons such as history server is using SPARK_DIST_CLASSPATH
(https://spark.apache.org/docs/latest/hadoop-provided.html) but this I presume
is a distribution classpath. It would be nice to have a similar config like
spark.driver.extraClasspath for launching daemons similar to history server.
