 private Map<String, Context> sourceContextMap;
    private Map<String, Context> sinkContextMap;
    private Map<String, Context> channelContextMap;
    private Map<String, Context> sinkGroupContextMap;
 
 
 sourceContextMap包含<c1,<type,spooldiry>
                    <spooldir,/home/hadoop/software/flume/lihao>>
                    ....

Similarly, several other similar

 if (srcConf == null) {
          srcConf = new Context();
          sourceContextMap.put(name, srcConf);
        }

        srcConf.put(cnck.getConfigKey(), value);
        return true;
      }

Cnetext中包含的是<c1：<type,spooldiry> <spooldir,/home/hadoop/software/flume/lihao>,r1:<>,s1:<>>

    private final Map<String, ComponentConfiguration> sourceConfigMap;
    private final Map<String, ComponentConfiguration> sinkConfigMap;
    private final Map<String, ComponentConfiguration> channelConfigMap;
    private final Map<String, ComponentConfiguration> sinkgroupConfigMap;

channelConfigMap stores <channelName,conf (component instance)> Others are the same
