-------------------------------
Summary: INSERT OVERWRITE LOCAL DIRECTORY writes staging files to
wrong hdfs directory
Key: HIVE-28473
URL: https://issues.apache.org/jira/browse/HIVE-28473
Project: Hive
Issue Type: Bug
Affects Versions: 3.1.3
Environment: Hadoop 3.3.4
HIVE 3.1.3
mapreduce engine
Reporter: liang yu
using HIVE 3.1.3 ; mr engine.
sql context:
insert overwrite local directory "/path/to/local/dir"
select a from table group by a;
when I run this sql in hive, it throws exception:
RuntimeException: cannot create staging directory
"hdfs://nameservice/path/to/local/dir/.hive-stagingxxxx".
the staging file should be written to a temp hdfs directory which is created
from hiveSessionPath and executionId, but in this scenario, it writes to a hdfs
directory which is created from the local directory path.
