无法在Phoenix View中查看列

本文介绍了无法在Phoenix View中查看列的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我在HBase中有一个推特表，请在下面找到它的描述，使用hbase describe tweet

I have a tweet table in HBase,Please find below it's description using hbase describe tweet

{NAME => 'tweets', DATA_BLOCK_ENCODING => 'NONE', BLOOMFILTER => 'ROW', REPLICAT
ION_SCOPE => '0', COMPRESSION => 'GZ', VERSIONS => '1', TTL => 'FOREVER', MIN_VE
RSIONS => '0', KEEP_DELETED_CELLS => 'FALSE', BLOCKSIZE => '65536', IN_MEMORY =>
 'false', BLOCKCACHE => 'true'}

并在Phoenix中创建了相应的视图

and created it's corresponding view in Phoenix as

 CREATE VIEW "tweets" ( pk VARCHAR PRIMARY KEY,"tweets".fromuser VARCHAR );

但是当我做 Select * fromtweets，我只能看到主键，来自用户列的数据是空的，同样的事情发生在我做的时候

But when i do Select * from "tweets" ,I can see only primary keys,fromuser column data is empty ,same thing happens when i do

select fromuser from "tweets"

推荐答案

创建视图时，必须双引号列名称以及列名称：

When creating your views you have to double quote the column family name as well as the column's name:

CREATE VIEW "tweets" ( pk VARCHAR PRIMARY KEY,"tweets"."fromuser" VARCHAR );

所以在上面的示例中，您需要在fromuser周围放置双引号。

So in your example above you need to put double quotes around "fromuser".
