             Summary: RDD/Storage metrics don't update cached partition counts when executors are removed/lost
                 Key: SPARK-9195
                 URL: https://issues.apache.org/jira/browse/SPARK-9195
             Project: Spark
          Issue Type: Bug
          Components: Web UI
    Affects Versions: 1.4.1
            Reporter: Ryan Williams
            Priority: Minor


I have an RDD that was cached, and then i lost most of my executors (in this case it was due to the executors having been dynamically-allocated and timing out, but this applies when the executors are lost in general).

The RDD page correctly shows that most of the RDD is no longer cached:

(However, the "Cached Partitions" count at the top is incorrect).

Additionally, the storage page still shows it as 100% cached:
