-----------------------------
Summary: Fix random hangs in SparkConnectJdbcDataTypeSuite (was: Fix
random hangs in SparkConnectJdbcDataTypeSuite by discarding stdout/stderr)
> Fix random hangs in SparkConnectJdbcDataTypeSuite
> -------------------------------------------------
>
> Key: SPARK-54551
> URL: https://issues.apache.org/jira/browse/SPARK-54551
> Project: Spark
> Issue Type: Sub-task
> Components: SQL
> Affects Versions: 4.1.0
> Reporter: Vinod KC
> Priority: Major
>
> When running `SparkConnectJdbcDataTypeSuite` test cases in non-debug mode,
> the child server process spawned for these tests can randomly block on
> write() calls when the stdout/stderr pipe buffers fill up.
> This occurs because the output streams are not being consumed, causing the
> process to hang indefinitely. The issue manifests intermittently depending on
> how much output the server generates during different test runs.
