我有hadoopversion2.6.3和pig-0.6.0，所有的守护进程都在单节点集群中运行。打完Pig的命令。Pig只连接到文件：///不是hdfs你能告诉我如何连接hdfs下面是我能看到的信息日志吗

2016-01-10 20:58:30,431 [main] INFO  org.apache.pig.backend.hadoop.executionengine.HExecutionEngine - Connecting to hadoop file system at: file:///
2016-01-10 20:58:30,650 [main] INFO  org.apache.hadoop.metrics.jvm.JvmMetrics - Initializing JVM Metrics with processName=JobTracker, sessionId=

当我咕哝着按命令的时候

grunt> ls  hdfs://localhost:54310/  
2016-01-10 21:05:41,059 [main] ERROR org.apache.pig.tools.grunt.Grunt - ERROR 2999: Unexpected internal error. Wrong FS: hdfs://localhost:54310/, expected: file:///
Details at logfile: /home/hguna/pig_1452488310172.log

我不知道它为什么需要文件：///

我是否正确配置了hadoop？或者有些地方我错了，请让我知道，如果有任何文件，我需要分享。我已经做了足够的研究无法修复它。顺便说一句，我是一个新手hadoop和Pig请帮助我。谢谢
