About the hicc start in eclipse

[RainerDun <de...@gmail.com>]

hello :

  I just started learning chukwa, and i want to build the chukwa source
code in eclipse ,but when i run the
org.apache.hadoop.chukwa.hicc.HiccWebServer to start the hicc service .
appeared some the following error tips:

12/06/18 21:01:34 INFO conf.ChukwaConfiguration:
chukwaConfis /home/rainerdun/project/chukwa-0.5.0/conf
12/06/18 21:01:35 INFO hicc.HiccWebServer: Initializing HICC Datastore.
12/06/18 21:01:35 INFO
hicc.HiccWebServer:file:/home/rainerdun/workspace/chukwa-0.5.0/bin/descriptors
12/06/18 21:01:35 ERROR hicc.HiccWebServer: HDFS unavailable, check
configuration in chukwa-env.sh.
12/06/18 21:01:35 ERROR util.PidFile: Delete pid file, No such file or
directory: /home/rainerdun/project/chukwa-0.5.0/var/run/hicc.pid
12/06/18 21:01:35 ERROR util.PidFile: Delete pid
filefailed, /home/rainerdun/project/chukwa-0.5.0/var/run/hicc.pid

 In  getResourceListing("descriptors")  method :
 public List<String> getResourceListing(String path) throws
URISyntaxException, IOException {
    ClassLoader contextClassLoader =
Thread.currentThread().getContextClassLoader();

    URL dirURL = contextClassLoader.getResource(path);

    if (dirURL == null) {
      dirURL = contextClassLoader.getResource(path);
        
    }
    if (dirURL.getProtocol().equals("jar")) {
    .....

   }

Call dirURL.getProtocol()，My result is 'file',but not 'jar' 。i don't
know how and which this  'jar' to load to the classpath in the if
condition(dirURL.getProtocol().equals("jar")） ，.but for the error
tips, i have already set the parameter as the  according to the official
document。so please tell me some advices about this problem 。very
appreciated...
