Question

我使用hive创建hbase表A的外部表B.我可以成功访问B.的数据。然后我按照官方指南输入Imapla Shell：

invalidate metadata B;

然后我在Impala Shell中查询这个外部表B：

select * from B limit 4;

但输出：

ERROR: RuntimeException: couldn't retrieve HBase table (mv_p2pusers) info:
Enable/Disable failed

以下是一些相关的日志：

似乎hbase表B既可以启用也可以禁用，非常奇怪。我用google搜索，这是否与hbase安全问题或impala版本问题有关？

有没有人遇到过同样的问题？如何解决这个问题？提前谢谢。

Answer 1

从Impala配置启用HBase服务。

你可以从Cloudera经理，Imapala-＆gt;配置中做到这一点从＆＃34; Hbase＆＃34;中搜索并启用该服务。 PFA。

为什么Impala没有在hbase表上工作？
