问题描述

我创建了一个表格，由

I created a table by

create 'tablename', 'columnfamily1'

现在是否可以添加另一个列族columnfamily2？什么是方法？

Now is it possible to add another column family 'columnfamily2'? What is the method?

推荐答案

看来

It seems

alter 'tablename', 'columnfamily2'

可以先禁用'tablename'。但是，即使启用它也可以正常工作。

does the trick. One may, disable 'tablename' first. However, it works fine even if enabled.

hbase(main):015:0> alter 'tablename', {NAME=> 'columnfamily2'}
Updating all regions with the new schema...
0/1 regions updated.
1/1 regions updated.
Done.
