---------------------------------
Summary: Improve error messaging when launching py4j gateway server
Key: FLINK-30962
URL: https://issues.apache.org/jira/browse/FLINK-30962
Project: Flink
Issue Type: Improvement
Components: API / Python
Reporter: Juntao Hu
Fix For: 1.18.0
In some cases, e.g. JVM_ARGS does not match the java executable version that
pyflink uses when launching py4j gateway server, there'll be only a general
message "Exception: Java gateway process exited before sending its port
number". It would be easier to investigate the error cause if we expose stderr
from java process.
