> Note that in order for the Spark UI to show the value of the custom metric, the custom metric class must be available in the classpath of the Spark History Server. The simplest way to do this is to put the Iceberg Spark runtime JAR in the SHS classpath. Spark's `SQLAppStatusListener` loads the custom metric class by name, instantiates it, and calls its `aggregateTaskMetrics` method to get the value of the metric. If it is not able to load the custom metric class, it shows "N/A". Yeah I was very frustrated with this when i was messing with it. Makes it hard if your history server is not running the same Spark build as your apps :( -- This is an automated message from the Apache Git Service.
