------------------------------------
Summary: Spark UI should sort jobs/stages with the completed
timestamp before cleaning up them
Key: SPARK-23307
URL: https://issues.apache.org/jira/browse/SPARK-23307
Project: Spark
Issue Type: Bug
Components: Web UI
Affects Versions: 2.3.0
Reporter: Shixiong Zhu
When you have a long running job, it may be deleted from UI quickly when it
completes, if you happen to run a small job after it. It's pretty annoying when
you run lots of jobs in the same driver concurrently (e.g., running multiple
Structured Streaming queries). We should sort jobs/stages with the completed
timestamp before cleaning up them.
In 2.2, Spark has a separated buffer for completed jobs/stages, so it doesn't
need to sort the jobs/stages.
What the behavior I expect:
Set "spark.ui.retainedJobs" to 10 and run the following codes, job 0 should be
kept in the Spark UI.
{code}
new Thread() {
override def run() {
// job 0
sc.makeRDD(1 to 1, 1).foreach { i =>
Thread.sleep(10000)
}
}
}.start()
Thread.sleep(1000)
for (_ <- 1 to 20) {
new Thread() {
override def run() {
sc.makeRDD(1 to 1, 1).foreach { i =>
}
}
}.start()
}
Thread.sleep(15000)
sc.makeRDD(1 to 1, 1).foreach { i =>
}
{code}
