【问题描述】:
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。我还可以启动我的 Hbase (sudo ./bin/start-hbase.sh) 和本地区域服务器 (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
HBase Shell; enter 'help<RETURN>' for list of supported commands.
Type "exit<RETURN>" to leave the 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:.*'
以下是我的 HBase 和 Hadoop 配置文件:

【问题讨论】:
-
您解决了这个问题吗?如果是,请您分享解决方案。
-
尝试删除zookeeper写入数据的目录。然后重启你的 HBase
-
在我的例子中,目录是 /teaching/14f-cis655/tmp/zk-deploy
