Question

我使用CTAS从现有表（订单）创建了一个Parquet表（orders_parquet），如下所示：

CREATE TABLE orders_parquet
ROW FORMAT SERDE 'org.apache.hadoop.hive.ql.io.parquet.serde.ParquetHiveSerDe'
STORED AS INPUTFORMAT 'org.apache.hadoop.hive.ql.io.parquet.MapredParquetInputFormat'
OUTPUTFORMAT 'org.apache.hadoop.hive.ql.io.parquet.MapredParquetOutputFormat'
AS SELECT * FROM orders;

正在下面加载

Total jobs = 3

Number of reduce tasks is set to 0 since there's no reduce operator

但是这个表加载了数据。请你帮忙解决错误的原因？

Answer 1

Hive需要在/ tmp位置写入权限才能记录信息。在你的情况下，hive没有/tmp/parquet-3.log的写权限。以 chmod 777 /tmp/parquet-3.log

为给定文件授予写入权限
