jackycchen opened a new issue #1767:
URL: https://github.com/apache/shardingsphere-elasticjob/issues/1767
## Feature Request
### Is your feature request related to a problem?
Code location: YamlEngine.java#marshal
`public static String marshal(final Object value) {
return new Yaml(new ElasticJobYamlRepresenter()).dumpAsMap(value);
}`
The function dumpAsMap detail is :
`public String dumpAsMap(Object data) {
return this.dumpAs(data, Tag.MAP, FlowStyle.BLOCK);
}`
Problem is **data format incompatible**
When the third parameter is FlowStyle.BLOCKļ¼the result of function dumpAsMap
is yaml format string
When set third parameter to null, the the result of function dumpAsMap is
json format string
I found that elasticjob client store the config of a task in zookeeper is
json format string in the older version(**like 2.1.5**), this will lead to
incompatible with the current version.
### Describe the feature you would like.
**should modify the function dumpAsMap like this:**
`public String dumpAsMap(Object data) {
return this.dumpAs(data, Tag.MAP, null);
}`
I think the data format should not be incompatible, thus will cause
difficult to upgrade.
