             Summary: Add support for trimming stack traces in user-facing components
                 Key: FLINK-18159
                 URL: https://issues.apache.org/jira/browse/FLINK-18159
             Project: Flink
          Issue Type: New Feature
          Components: Command Line Client, Runtime / REST
            Reporter: Chesnay Schepler
             Fix For: 1.12.0


Add a verbosity query parameter / flag(==config option) into the REST API / CLI to trim the exception stack traces, which means excluding the location information.

The result would be something like this:
{code}
org.apache.flink.runtime.client.JobSubmissionException: Failed to submit job.
Caused by: java.lang.RuntimeException: org.apache.flink.runtime.client.JobExecutionException: Could not set up JobManager
Caused by: org.apache.flink.runtime.client.JobExecutionException: Could not set up JobManager
Caused by: java.io.FileNotFoundException: Cannot find checkpoint or savepoint file/directory 'ashudasd' on file system 'file'.
{code}

This approach renders even the biggest stack traces fairly readable, and is rather convenient since it only requires changes in the actual user-facing components.

Logging would not be impacted by this.

The trimming was already implemented in this [PR|https://github.com/apache/flink/pull/12392], but the flags are missing.
