liuxuedongcn opened a new issue #4496:
URL: https://github.com/apache/incubator-dolphinscheduler/issues/4496
The hdfs path mapped when hive adds partitions is passed in by custom
parameters:
Sample statement: alter table test add if not exists partition(dt='${time}')
location "/.../${time}/";
Custom parameters：time in varchar $[yyyy-MM-dd]
Problem Description：
Quotation marks are added to the custom parameters in the Hive load
partition SQL, which causes the partition path mapping error:
before modification: location "/.../${time}/" Is parsed into location
"/.../'2020-01-19'/"
After modification : location "/.../${time}/" Is parsed into location
"/.../2020-01-19/"
After the modification, there are no quotation marks in the hdfs path, which
meets the requirements of the partition of the hive table
--------------------------------------------------------------------------------------------------------------
hive添加分区时所映射的hdfs路径由自定义参数传入
样例语句：alter table test add if not exists partition(dt='${time}') location
"/.../${time}/";
自定义参数：time in varchar $[yyyy-MM-dd]
问题描述：
Hive加载分区SQL里的自定义参数上加了引号，导致分区路径映射错误：
修改前 location "/.../${time}/ 被解析成 location "/.../'2020-01-19'/
修改后 location "/.../${time}/ 被解析成 location "/.../2020-01-19/
修改后hdfs路径中不再有引号，符合hive表的分区的需求
