[SPARK-47573][K8S] Support custom driver log url #45728

EnricoMi · 2024-03-26T18:56:45Z

What changes were proposed in this pull request?

Add config spark.ui.custom.driver.log.url to Kubernetes resource manager allow setting log url templates similar to spark.ui.custom.executor.log.url.

Allows for

--conf spark.ui.custom.driver.log.url="https://my-custom.url/api/logs?applicationId={{APP_ID}}

Supports these variables:

APP_ID: The unique application id
KUBERNETES_NAMESPACE: The namespace where the executor pods run
KUBERNETES_POD_NAME: The name of the pod that contains the executor
FILE_NAME: The name of the log, which is always "log"

Adds driver pod environment variable SPARK_DRIVER_POD_NAME.

Why are the changes needed?

Running Spark on Kubernetes requires persisting the logs elsewhere. Having the Spark UI link to those logs is very useful. This should be possible for driver logs similar to executor logs.

Does this PR introduce any user-facing change?

Spark UI provides links to logs when run on Kubernetes.

How was this patch tested?

Unit test and manually tested on minikube K8S cluster.

Was this patch authored or co-authored using generative AI tooling?

No

Sorry for being late. For the live log, can we try to use Spark Driver Live Log instead?

spark.driver.log.localDir=/tmp/logs

Apache Spark 4.0.0-preview1

EnricoMi · 2024-08-14T07:25:08Z

@dongjoon-hyun thanks for the pointer! Is the live log supported by the Spark History Server? Or are they only available during runtime of the Spark app? Are they log collected? Executor logs are links to the log collections service but driver logs are not? Sounds different to the spark.ui.custom.executor.log.url approach.

EnricoMi · 2024-08-14T18:12:17Z

Looks like the Spark History Server does not contain that live log tab. How is this then an equivalent replacement for the proposed driver log url?

This PR allows for the log link for the driver in the executors tab:

dongjoon-hyun · 2024-08-14T18:17:29Z

It's not the same of course, @EnricoMi .

Looks like the Spark History Server does not contain that live log tab. How is this then an equivalent replacement for the proposed driver log url?

What I wrote is For the live log, can we try to use Spark Driver Live Log instead?. Nothing more.
Have you use Apache Spark's Driver log feature before, @EnricoMi ?

EnricoMi · 2024-08-15T05:34:24Z

Haven't seen the live log feature before.

dongjoon-hyun · 2024-08-15T06:15:17Z

Ya, maybe I made you confused.

I didn't review this PR yet.
I visited SPARK-49149 first and checked the code.
- After that, I searched the PR list and see your executor log PR.
- Then, it lead me to here (driver log PR).

The Dirver Live UI feature is only a part of the following at Spark 4.

https://issues.apache.org/jira/browse/SPARK-45869 (Revisit and Improve Spark Standalone Cluster)

So, it is not relevant to this PR technically.

EnricoMi · 2024-08-15T07:16:57Z

Thanks for clarification.

dongjoon-hyun · 2024-08-15T07:30:36Z

Let me reopen this for now because it seems to be closed by the bot.

EnricoMi · 2024-08-23T08:05:06Z

@dongjoon-hyun any thoughts on this?

EnricoMi · 2024-09-02T09:12:34Z

@dongjoon-hyun can we get this into the Spark 4.0.0 release?

dongjoon-hyun · 2024-09-12T15:59:07Z

Let me check this PR quickly since I'm currently preparing Apache Spark 4.0.0-preview2, @EnricoMi .

dongjoon-hyun · 2024-09-12T16:00:22Z

core/src/main/scala/org/apache/spark/internal/config/UI.scala

    .stringConf
    .createOptional

+  val CUSTOM_DRIVER_LOG_URL = ConfigBuilder("spark.ui.custom.driver.log.url")


Since this doesn't have spark.kubernetes. prefix, this is supposed to work with YARN, @EnricoMi . Are you sure?

This was just derived from spark.ui.custom.executor.log.url, where I suspect this should be similar. The property name does not mention Yarn, and documentation says that only K8s support this.
