在 AWS Athena 中创建存储桶 table

Question

我尝试通过以下查询创建存储桶 table 但失败了。但是，如果我删除 CLUSTERED BY 子句，查询成功。有什么建议吗？谢谢。

错误信息：no viable alternative at input create external

CREATE EXTERNAL TABLE nation5(
  n_nationkey bigint, 
  n_name string, 
  n_rgionkey int, 
  n_comment string)
CLUSTERED BY 
  n_regionkey INTO 256 BUCKETS
ROW FORMAT SERDE 
  'org.apache.hadoop.hive.ql.io.parquet.serde.ParquetHiveSerDe' 
WITH SERDEPROPERTIES ( 
  'path'='s3://test/testbucket/nation5/') 
STORED AS INPUTFORMAT 
  'org.apache.hadoop.hive.ql.io.parquet.MapredParquetInputFormat' 
OUTPUTFORMAT 
  'org.apache.hadoop.hive.ql.io.parquet.MapredParquetOutputFormat'
LOCATION
  's3://test/testbucket/nation5/'

Answer 1

CLUSTERED BY栏需要在括号内，以下作品：

CREATE EXTERNAL TABLE test.nation5(
  n_nationkey bigint, 
  n_name string, 
  n_regionkey int, 
  n_comment string)
CLUSTERED BY 
  (n_regionkey) INTO 256 BUCKETS
ROW FORMAT SERDE 
  'org.apache.hadoop.hive.ql.io.parquet.serde.ParquetHiveSerDe' 
WITH SERDEPROPERTIES ( 
  'path'='s3://test/testbucket/nation5/') 
STORED AS INPUTFORMAT 
  'org.apache.hadoop.hive.ql.io.parquet.MapredParquetInputFormat' 
OUTPUTFORMAT 
  'org.apache.hadoop.hive.ql.io.parquet.MapredParquetOutputFormat'
LOCATION
  's3://test/testbucket/nation5/'

（您在列定义中的 n_rgionkey 中也存在拼写错误。
