在Impala中实现CREATE AS SELECT

Question

请帮助我了解如何实施CREATE TABLE AS SELECT

简单create table t1 as select * from t2;我可以实现

Create table t1 like t2;
insert into t1 as select * from t2;

但是如何实施create table t1 as select c1,c2,c3 from t2;

有没有办法在impala中实现这个？

正如评论中所提到的，从1.2开始，Impala支持CREATE TABLE AS SELECT：documentation，JIRA ticket。
