[jira] [Updated] (SPARK-8895) MetricsSystem.removeSource not called
in StreamingContext.stop
[ https://issues.apache.org/jira/browse/SPARK-8895?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Aniket Bhatnagar updated SPARK-8895:
------------------------------------
Description:
StreamingContext calls env.metricsSystem.registerSource during its construction but does not call env.metricsSystem.removeSource. Therefore, if a user attempts to restart a Streaming job in the same JVM by creating a new instance of StreamingContext with the same application name, it results in exceptions like the following in the log:
{quote}
[info] o.a.s.m.MetricsSystem -Metrics already registered
java.lang.IllegalArgumentException: A metric named <>.StreamingMetrics.streaming.lastReceivedBatch_processingEndTime already exists
