Here is my solution:
The definition of the 'call' method can be adjusted like this:
```java
@ProcedureHint(
argument = {
@ArgumentHint(
name = "rebalanceId",
type = @DataTypeHint("STRING"),
isOptional = true)
},
output =
@DataTypeHint(
"ROW<rebalance_id STRING, rebalance_status
STRING, rebalance_progress STRING, rebalance_plan STRING>"))
public Row[] call(ProcedureContext context, @Nullable String
rebalanceId) throws Exception
```
The content of the `rebalance_plan` field is the JSON-formatted string of
`RebalanceResultForBucket.plan` list in the result, like:
```java
for (RebalanceResultForBucket resultForBucket : bucketMap.values()) {
result.add(resultForBucket.plan());
}
```
Because `rebalanceStatus` already exists.
