--------------------------------
Summary: Fix random hangs in SparkConnectJdbcDataTypeSuite by
discarding stdout/stderr
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
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.
