Ryan Williams created SPARK-5778: ------------------------------------ Summary: Throw if nonexistent "spark.metrics.conf" file is provided Key: SPARK-5778 URL: https://issues.apache.org/jira/browse/SPARK-5778 Project: Spark Issue Type: Improvement Components: Spark Core Affects Versions: 1.2.1 Reporter: Ryan Williams Priority: Minor
Spark looks for a {{MetricsSystem}} configuration file when the {{spark.metrics.conf}} parameter is set, [defaulting to the path "{{metrics.properties}}" when it's not set|https://github.com/apache/spark/blob/466b1f671b21f575d28f9c103f51765790914fe3/core/src/main/scala/org/apache/spark/metrics/MetricsConfig.scala#L52-L55]. In the event of a failure to find or parse the file, [the exception is caught and an error is logged|https://github.com/apache/spark/blob/466b1f671b21f575d28f9c103f51765790914fe3/core/src/main/scala/org/apache/spark/metrics/MetricsConfig.scala#L61]. This seems like reasonable behavior in the general case where the user has not specified a {{spark.metrics.conf}} file. However, I've been bitten several times by having specified a file that all or some executors did not have present (I typo'd the path, or forgot to add an additional {{--files}} flag to make my local metrics config file get shipped to all executors), the error was swallowed and I was confused about why I'd captured no metrics from a job that appeared to have run successfully. I'd like to change the behavior to actually throw if the user has specified a configuration file that doesn't exist. -- 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
