Question

是否有人尝试在Sequence Files上创建AWS Athena Table。根据{{3}}看来它是可能的。我能够在create table statement下面执行。

   create external table if not exists sample_sequence (
      account_id string,
      receiver_id string,
      session_index smallint, 
      start_epoch bigint)
STORED AS sequencefile
location 's3://bucket/sequencefile/';

语句执行成功但当我尝试从表中读取数据时，它会抛出错误

Answer 1

序列文件是有效的。这里的问题是没有定义分隔符。

即行格式分隔的以结尾的字段缺失

如果在您的情况下，如果tab是列分隔符，则行数据在下一行中，它将是

head

AWS Athena是否支持序列文件
