Imran Rashid created SPARK-6980:
-----------------------------------
Summary: Akka timeout exceptions indicate which conf controls them
Key: SPARK-6980
URL: https://issues.apache.org/jira/browse/SPARK-6980
Project: Spark
Issue Type: Improvement
Components: Spark Core
Reporter: Imran Rashid
Priority: Minor
If you hit one of the akka timeouts, you just get an exception like
{code}
java.util.concurrent.TimeoutException: Futures timed out after [30 seconds]
{code}
The exception doesn't indicate how to change the timeout, though there is
usually (always?) a corresponding setting in {{SparkConf}} . It would be nice
if the exception including the relevant setting.
I think this should be pretty easy to do -- we just need to create something
like a {{NamedTimeout}}. It would have its own {{await}} method, catches the
akka timeout and throws its own exception.
