> When we use CTAS to create a new table in s3, the table location is not set correctly.
As a result, the data from the existing table cannot be inserted into the new created table.
> We can use the following example to reproduce this issue.
> set hive.metastore.warehouse.dir=OUTPUT_PATH;
> drop table s3_dir_test;
> drop table s3_1;
> drop table s3_2;
> create external table s3_dir_test(strct struct<a:int, b:string, c:string>)
> row format delimited
> fields terminated by '\t'
> collection items terminated by ' '
> location 'INPUT_PATH';
> create table s3_1(strct struct<a:int, b:string, c:string>)
> row format delimited
> fields terminated by '\t'
> collection items terminated by ' ';
> insert overwrite table s3_1 select * from s3_dir_test;
> select * from s3_1;
> create table s3_2 as select * from s3_1;
> select * from s3_1;
> select * from s3_2;
> The data could be as follows.
> 1 abc 10.5
> 2 def 11.5
> 3 ajss 90.23232
> 4 djns 89.02002
> 5 random 2.99
> 6 data 3.002
> 7 ne 71.9084
> The root cause is that the SemanticAnalyzer class did not handle s3 location properly
for CTAS.
> A patch will be provided shortly.
