在使用HBase过程中,有时会遇到表显示不存在的情况,本文将介绍这种情况的原因和解决方法。 原因分析 表显示不存在的情况可能由以下原因引起: 表尚未创建:在访问表之前,需要先创建表。如果尚未创建表,就会显示不存在。下面是创建HBase表的示例代码: create 'mytable', 'cf1', 'cf2' 1. 表名拼写错误:请检查表...

The table kylin_metadata does not exist in meta but has a znode. run hbck to fix inconsistencies. 解决步骤: (1) 进入zookeeper/bin运行zkCli.sh模式 (如果是用hbase自带的zk可以执行指令: hbase zkcli ) (2) ls /hbase/table命令查看是否有bigdata这个表 ...

For example, if you specify HBASE TABLE NAME hbasetable1, but the actual HBase table name is HBaseTable1, the statement returns an error indicating that the HBase table does not exist. If your HBase table names are similar, such as hbasetable1 and HBaseTable1 except for the case,...
