-------------------------------
Summary: Add a check for host name
Key: SPARK-23651
URL: https://issues.apache.org/jira/browse/SPARK-23651
Project: Spark
Issue Type: Improvement
Components: Spark Core
Affects Versions: 2.4.0
Reporter: liuxian
I encountered a error like this:
_org.apache.spark.SparkException: Invalid Spark URL:
spark://HeartbeatReceiver@ci_164:42849_
_at
org.apache.spark.rpc.RpcEndpointAddress$.apply(RpcEndpointAddress.scala:66)_

_at

_at
org.apache.spark.scheduler.TaskSchedulerImpl.start(TaskSchedulerImpl.scala:164)_
I didn't know why this _URL_(spark://HeartbeatReceiver@ci_164:42849) is
invalid, so i think we should give a clearer reminder for this error.
