zjjiang updated FLINK-36620:
----------------------------
Description:
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.
