我用了命令
hdfs dfs -du -h /hbase/data/default/
如这里所示:查看hbase表的大小。但是,输出中有两个数字,如下例所示:
... 2.7 M 8.1 M /hbase/data/default/rTblCM_opt 9.4 M 28.2 M /hbase/data/default/rTblCM_std
这些数字的含义是什么?
谢谢
我是hbase的新手。在hbase中创建了30个表。我想查看这些表结构。
我使用下面的命令查看这些表,但只有一个表。希望我需要连接到hbase中的正确数据库来列出表格。
hbase(main):017:0> list
TABLE
test
1 row(s) in 0.0140 seconds
现在,我想让命令知道hbase中存在(已经创建)的数据库是什么
在Clojure中,如果我想要使用hbase测试实用程序启动一个测试集群,我必须用以下命令注释我的依赖项:
[org.apache.hbase/hbase "0.92.2" :classifier "tests" :scope "test"]
首先,我不知道这是什么意思。根据leiningens样本project.clj

我试图在cloudera (5.5)中查询HBase,但得到以下异常:
Error connecting HBase: org.apache.hadoop.hbase.MasterNotRunningException: com.google.protobuf.ServiceException: org.apache.hadoop.net.ConnectTimeoutException: 20000 millis timeout while waiting for channel to be ready for connect. ch : java.nio.channels.SocketCha
我在独立模式下运行HBase,并得到以下错误。
2016-10-05 16:29:06,268 ERROR [main] client.ConnectionManager$HConnectionImplementation: The node /hbase is not in ZooKeeper

我试图从java客户端创建HBase模式,但它抛出了以下异常:

我正试图在windows中使用HBase,而且我对它还很陌生。当我试图运行文件start-hbase.cmd时,我得到了以下错误

Error: Could not create the Java Virtual Machine.

我看到了一个存储HBase数据的外部Hive表:
CREATE EXTERNAL TABLE IF NOT EXISTS ods.demo_table(
rowkey String COMMENT 'rowkey of hbase',
....
)
STORED BY 'org.apache.hadoop.hive.hbase.HBaseStorageHandler' WITH SERDEPROPERTIES ("hbase.columns.mapping" = "info:...") TBLPROPER
访问hbase的应用程序在尝试创建hbase表的实例时产生错误。这曾经工作得很好,但是hbase服务器升级了,随后我不得不更新java客户端。

我想安装hbase 1.2.4。当我尝试运行bin/start-hbase.sh时,我得到以下警告。

hbase shell命令生成大量众所周知的zookeeper异常...

我试图在hbase之上构建一个web服务,因此代码看起来大致如下:
@GET
@Path("/blabla")
@Override
public List<String> getEvents($$$params$$$) {
......
//calling hbase query the events
......
}
当Hbase服务关闭时,hbase Java API继续重新尝试连接到Hbase区域服务器,最终超时并抛出RT异常:
