--------------------------------
Summary: Fix Incorrect assertion of "master/worker web ui
available behind front-end reverseProxy" in MasterSuite
Key: SPARK-35004
URL: https://issues.apache.org/jira/browse/SPARK-35004
Project: Spark
Issue Type: Bug
Components: Tests
Affects Versions: 3.2.0
Reporter: Yang Jie
[https://github.com/apache/spark/blob/bfba7fadd2e65c853971fb2983bdea1c52d1ed7f/core/src/test/scala/org/apache/spark/deploy/master/MasterSuite.scala#L425]
{code:java}
// with LocalCluster, we have masters and workers in the same JVM, each
overwriting
// system property spark.ui.proxyBase.
// so we need to manage this property explicitly for test
System.getProperty("spark.ui.proxyBase") should startWith
(s"$reverseProxyUrl/proxy/worker-") // Line 425
{code}
Line 425 in MasterSuite is considered as unused expression, If we merge lines
424 and 425 into one：
{code:java}
System.getProperty("spark.ui.proxyBase") should startWith
(s"$reverseProxyUrl/proxy/worker-")
{code}
this assertion will fail:
{code:java}
- master/worker web ui available behind front-end reverseProxy *** FAILED ***
The code passed to eventually never returned normally. Attempted 45 times
over 5.091914027 seconds. Last failure message:
"http://proxyhost:8080/path/to/spark"; did not start with substring
"http://proxyhost:8080/path/to/spark/proxy/worker-";. (MasterSuite.scala:405)
