yaooqinn opened a new pull request, #54171:
URL: https://github.com/apache/spark/pull/54171
### What changes were proposed in this pull request?
This PR fixes a typo in `RDDOperationGraph.scala` where an extra `}`
character was accidentally added to the DOT node label string, causing the DAG
visualization to fail rendering in both Jobs and Stages pages of the Spark Web
UI.
**Before (broken):**
```scala
s"""${node.id} [id="node_${node.id}" labelType="html" label="$label}"]"""
```
**After (fixed):**
```scala
s"""${node.id} [id="node_${node.id}" labelType="html" label="$label"]"""
```
### Why are the changes needed?
The DAG visualization in the Spark Web UI is completely broken. Instead of
rendering the graph, it shows the raw DOT source text. This affects both Jobs
and Stages views across all browsers (Firefox, Edge, Chrome) and both Spark
Shell and PySpark.
This regression was introduced in SPARK-45274 (PR #43053).
### Does this PR introduce _any_ user-facing change?
Yes. The DAG visualization in the Spark Web UI will render correctly again.
**Before:** Raw DOT graph source displayed instead of visualization
**After:** Properly rendered DAG graph
### How was this patch tested?
- Existing unit tests pass: `RDDOperationGraphSuite`, `UISeleniumSuite` (DAG
visualization test)
- Manual verification with `sc.range(0, 10, 1, 4).count()` in spark-shell
### Was this patch authored or co-authored using generative AI tooling?
No.
