[KAFKA-8310] CommandLineUtils.parseKeyValueArgs --property flag too greedy when splitting key=value pairs - ASF JIRA

The CommandLineUtils split apart all equal signs in the key-value pair rather than just the first, therefore making something like this fail.

--property value.schema='{"name":"foo", "type":"string", "doc": "key=value"}'

as it tries to assign these two properties separately

{"name":"foo", "type":"string", "doc": "key

value"}

Issue here

Ideally, the code should do something like indexOf("="), to get the first one, then substring from there.
