配置一下hbase Master试试 configuration.set("hbase.master", "IP:60000");
加那个也没有用，反编译了下hbase的jar，发现是下面这块报的空指针
 ClassLoader cl = HQuorumPeer.class.getClassLoader();
    InputStream inputStream = cl.getResourceAsStream("zoo.cfg");//报错

log4j的：WARN没有追加程序能够找到记录仪（org.apache.hadoop.metrics2.lib.MutableMetricsFactory）。 log4j的：WARN请正确初始化log4j的系统。 log4j的：WARN见http://logging.apache.org/log4j/1.2/faq.html#noconfig更多信息。 在线程异常“主要”显示java.lang.NullPointerException
