Aniket Bhatnagar created SPARK-8895: ---------------------------------------
Summary: MetricsSystem.removeSource not called in StreamingContext.stop Key: SPARK-8895 URL: https://issues.apache.org/jira/browse/SPARK-8895 Project: Spark Issue Type: Bug Components: Streaming Affects Versions: 1.4.0 Reporter: Aniket Bhatnagar Priority: Minor 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: [info] o.a.s.m.MetricsSystem -Metrics already registered java.lang.IllegalArgumentException: A metric named <>.StreamingMetrics.streaming.lastReceivedBatch_processingEndTime already exists at com.codahale.metrics.MetricRegistry.register(MetricRegistry.java:91)~[metrics-core-3.1.0.jar:3.1.0] at com.codahale.metrics.MetricRegistry.registerAll(MetricRegistry.java:385)~[metrics-core-3.1.0.jar:3.1.0] at com.codahale.metrics.MetricRegistry.register(MetricRegistry.java:85)~[metrics-core-3.1.0.jar:3.1.0] at org.apache.spark.metrics.MetricsSystem.registerSource(MetricsSystem.scala:148) ~[spark-core_2.11-1.4.0.jar:1.4.0] at org.apache.spark.streaming.StreamingContext.<init>(StreamingContext.scala:199) [spark-streaming_2.11-1.4.0.jar:1.4.0] at org.apache.spark.streaming.StreamingContext.<init>(StreamingContext.scala:71) [spark-streaming_2.11-1.4.0.jar:1.4.0] -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
