----------------------------------
Summary: Spark UI misses some executor metrics
Key: SPARK-28352
URL: https://issues.apache.org/jira/browse/SPARK-28352
Project: Spark
Issue Type: Bug
Components: Web UI
Affects Versions: 2.4.1
Reporter: Burak KÖSE
We have recently migrated our application from 2.2.1 to 2.4.1. We have realized
that Spark UI is missing some critical information or shows wrong ones.
We have a big cluster, with 80+ executors. It is Spark Streaming with customer
receivers. On Spark UI in storage tab, we can see memory blocks and their size.
This page shows correct information that we can see on Ganglia and host level
monitors. However, in executor tab, `RDD blocks` shows `0` while we have
thousands of them in memory. Moreover, `Storage Memory` shows incorrect numbers.
