Presto CLI调用system.create_empty_partition（）错误

Question

环境

• presto 0.215
• presto-cli 0.215
• presto-jdbc 0.215

Presto创建的配置单元表

CREATE TABLE hive.origin.test_part (
    id int,
    date_key int
)
WITH (
    format = 'ORC',
    partitioned_by = ARRAY['date_key'],
    external_location = '/user/hive/warehouse/origin.db/test_part/'
)

Presto JDBC和CLI均成功插入

partiton'20190122'之前不存在并成功插入，这意味着将 tmp 目录重命名为/user/hive/warehouse/origin.db/test_part/date_key=20190122成功。

/user/hive/warehouse/origin.db/test_part/date_key=20190122/在hdfs中

但是Presto CLI CALL system.create_empty_partition（）失败

CALL system.create_empty_partition( schema_name => 'origin', table_name => 'test_part', partition_columns => ARRAY['date_key'], partition_values => ARRAY['20190121'])

/tmp/presto-hive/在hdfs中

所以

CALL system.create_empty_partition（）使用不同的“用户”来操纵hdfs？

Answer 1

由于bug导致它无法使用未存储桶的表而导致的失败。在301版本中已修复。
