如何更改hbase表中的列族的名称 [英] how to change the name of column family in the hbase table

问题描述

我有一个只有1列族（cf1）的Hbase表格，下面有100列。我需要将cf1更改为新的列族（CF1）。

总之，我需要修改列名称。我已经通过以下链接 http：//comments.gmane。 org / gmane.comp.java.hadoop.hbase.user / 30959 ，但没用。

感谢您的提前。

解决方案

从家庭到家庭然后删除旧列家庭。如果有一个hbase客户端的API，我认为它也会这样做。因为写入到hbase文件的数据包含列名称。

I have a Hbase table with only 1 column family(cf1) having 100 columns under it. I need to change cf1 to new column family(CF1).

In short i need to modify column family name. I have gone through the following link http://comments.gmane.org/gmane.comp.java.hadoop.hbase.user/30959 but of no use.

Thanks in Advance.

解决方案

I think you should copy columns from family to family then delete old column family. If there was a hbase client api for that, it would do the same, i think. Because data written to hbase files contains column family name in it.
