zjjiang created FLINK-36620:
-------------------------------
Summary: Add support for the flink-home parameter to be set in
both “--flink-home $FLINK_HOME” and “--flink-home=$FLINK_HOME” formats
Key: FLINK-36620
URL: https://issues.apache.org/jira/browse/FLINK-36620
Project: Flink
Issue Type: Improvement
Components: Flink CDC
Affects Versions: cdc-3.1.1, cdc-3.2.0, cdc-3.1.0
Reporter: zjjiang
Fix For: cdc-3.3.0
Currently, most of FlinkCDC's command line arguments are supported in the
format "--$KEY $VALUE" or "--$KEY=$VALUE", e.g. --jar, but, except for flink-
home, which only supports space spacing. Users who use the
"--flink-home=$FLINK_HOME" format on the command line (trying to be consistent
with the other = spacing arguments) will not be able to set flink home
correctly.
In particular, when there is an environment variable $FLINK_HOME and you want
to override it by setting --flink-home=/path/to/new/flink/home, you will find
that it does not work.
We would like to support the flink-home parameter in both --flink-home
$FLINK_HOME and --flink-home=$FLINK_HOME formats, so that users can avoid
formatting differences and runtime exceptions when using command line arguments.
