我正在尝试使用以下命令启动 hbase：

hadoop@user-HP-dx2480-MT-NA125PA:/usr/local/hadoop/hbase$ bin/start-hbase.sh

并且启动失败并出现以下错误：

错误是 localhost：启动 zookeeper，登录到 /usr/local/hadoop/hbase/bin/../logs/hbase-hadoop-zookeeper-user-HP-dx2480-MT-NA125PA.out localhost：java.net.BindException：地址已在使用 localhost：在 sun.nio.ch.Net.bind(Native Method) localhost：在 sun.nio.ch.ServerSocketChannelImpl.bind(ServerSocketChannelImpl.java:137) localhost：在 sun.nio.ch.ServerSocketAdaptor。 bind(ServerSocketAdaptor.java:77) localhost: 在 sun.nio.ch.ServerSocketAdaptor.bind(ServerSocketAdaptor.java:70) localhost: 在 org.apache.zookeeper.server.NIOServerCnxn$Factory.(NIOServerCnxn.java:122) localhost ：在 org.apache.zookeeper.server.ZooKeeperServerMain.runFromConfig(ZooKeeperServerMain.java:106) 本地主机：在 org.apache.hadoop.hbase.zookeeper.HQuorumPeer.runZKServer(HQuorumPeer.java:85) 本地主机：在 org.apache.hadoop.hbase.zookeeper.HQuorumPeer.main(HQuorumPeer.java:70)

解决方案是什么？谁能给我打电话？什么是地址绑定异常？？

命令是 bin/start-all.sh

hadoop@user-HP-dx2480-MT-NA125PA:/usr/local/hadoop/hadoop$ bin/start-all.sh

错误是

mv: cannot move `/usr/local/hadoop/hadoop/bin/../logs/hadoop-hadoop-namenode-user-HP-dx2480-MT-NA125PA.out.4' to `/usr/local/hadoop/hadoop/bin/../logs/hadoop-hadoop-namenode-user-HP-dx2480-MT-NA125PA.out.5': Permission denied
mv: try to overwrite `/usr/local/hadoop/hadoop/bin/../logs/hadoop-hadoop-namenode-user-HP-dx2480-MT-NA125PA.out.4', overriding mode 0644 (rw-r--r--)? 
mv: try to overwrite `/usr/local/hadoop/hadoop/bin/../logs/hadoop-hadoop-namenode-user-HP-dx2480-MT-NA125PA.out.3', overriding mode 0644 (rw-r--r--)?

有什么解决办法吗？？

当我执行命令时ssh localhost（在 Ubuntu 10.10 中），它会显示错误消息“权限被拒绝（公钥）”。可能是什么问题？

有什么问题sshd_config file in /etc/ssh吗？应该PasswordAuthentication设置为no? 我已将 设置PasswordAuthentication为no，但它仍然给我错误“权限被拒绝（公钥）”。
