HBase 0.98.5无法在Windows上启动

我已经在Windows 7 PC上下载并安装了HBase 0.98.5.我按照Apache的Getting Started步骤进行了修改,base-site.xml如下所示(配置元素为空OOB):

    
    hbase.rootdir
    file:///c:/datastore/hbase
  
  
    hbase.zookeeper.property.dataDir
    c:/datastore/zookeper
  

启动HBase时,我收到以下错误:

通过查看ProcessBuilder#start()抛出异常的方法,似乎缺少一些参数:

public Process start() throws IOException {
        // Must convert to array first -- a malicious user-supplied
        // list might try to circumvent the security check.
        String[] cmdarray = command.toArray(new String[command.size()]);
        cmdarray = cmdarray.clone();

        for (String arg : cmdarray)
            if (arg == null)
                throw new NullPointerException(); // this is line 1010
        // Throws IndexOutOfBoundsException if command is empty
        String prog = cmdarray[0];

任何想法在这里可能是错的？
