Summary: Initial PR for Instrumentation improvements: UUID and logging levels Key: SPARK-23859 URL: https://issues.apache.org/jira/browse/SPARK-23859 Project: Spark Issue Type: Sub-task Components: ML Affects Versions: 2.3.0 Reporter: Joseph K. Bradley Assignee: Weichen Xu This is a subtask for an initial PR to improve MLlib's Instrumentation class for logging. It will address a couple of issues and use the changes in LogisticRegression as an example class. Issues: * The UUID is currently generated from an atomic integer. This is a problem since the integer is reset whenever a persisted Estimator is loaded on a new cluster. We should just use a random UUID to get a new UUID each time with high probability. * We use both Instrumentation and Logging to log stuff. Let's standardize around Instrumentation in MLlib since it can associate logs with the Estimator or Transformer which produced the logs (via a prefix with the algorithm's name or UUID). -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
