      Description

      Noticed that slowly, over the course of a day or two, heap memory usage on a long running spark process increased monotonically.
      After doing a heap dump and examining in jvisualvm, saw there were over 15M org.apache.spark.sql.execution.ui.SQLTaskMetrics objects allocated, taking over 500MB.
