---------------------------------

             Summary: Add missing "tableId" for SendToTableOperatorSpec in 
Samza job execution plan
                 Key: SAMZA-2547
                 URL: https://issues.apache.org/jira/browse/SAMZA-2547
             Project: Samza
          Issue Type: Bug
            Reporter: Alan Zhang
            Assignee: Alan Zhang


Currently, JobGraphJsonGenerator.operatorToMap() function populates "tableId" 
field when the given operator spec is table related. 

However, as shown in the below codes, we forgot to handle 
*SendToTableOperatorSpec*, but handle *StreamTableJoinOperatorSpec* twice 
somehow. 
{code:java}
private Map<String, Object> operatorToMap(OperatorSpec spec) {
    Map<String, Object> map = new HashMap<>();
    map.put("opCode", spec.getOpCode().name());
    map.put("opId", spec.getOpId());
    map.put("sourceLocation", spec.getSourceLocation());
    ...

   if (spec instanceof StreamTableJoinOperatorSpec) {
      String tableId = ((StreamTableJoinOperatorSpec) spec).getTableId();
      map.put("tableId", tableId);
    }

    if (spec instanceof StreamTableJoinOperatorSpec) {
      String tableId = ((StreamTableJoinOperatorSpec) spec).getTableId();
      map.put("tableId", tableId);
    }

    if (spec instanceof JoinOperatorSpec) {
      map.put("ttlMs", ((JoinOperatorSpec) spec).getTtlMs());
    }

    return map;
  }
{code}
