我正在尝试将我的hbase连接到hdfs。我的hdfs namenode（bin/hdfs namenode）和datnode（/bin/hdfs datanode）正在运行。我还可以启动hbase（sudo./bin/start hbase.sh）和本地服务器（sudo./bin/local-regionservers.sh start 1 2）。但是，当我尝试从hbase shell执行命令时，会出现以下错误：

cis655stu@cis655stu-VirtualBox:/teaching/14f-cis655/proj-dtracing/hbase/hbase-0.99.0-SNAPSHOT$ ./bin/hbase shell

Here is some help for this command:
List all tables in hbase. Optional regular expression parameter could
be used to filter the output. Examples:

  hbase> list
  hbase> list 'abc.*'
  hbase> list 'ns:abc.*'
  hbase> list 'ns:.*'
