[SPARK-29174][SQL] Support LOCAL in INSERT OVERWRITE DIRECTORY to data source by ajithme · Pull Request #27039 · apache/spark

ajithme · 2019-12-29T07:23:53Z

What changes were proposed in this pull request?

INSERT OVERWRITE LOCAL DIRECTORY is supported with ensuring the provided path is always using file:// as scheme and removing the check which throws exception if we do insert overwrite by mentioning directory with LOCAL syntax

Why are the changes needed?

without the modification in PR, insert overwrite local directory <location> using

throws exception

Error: org.apache.spark.sql.catalyst.parser.ParseException:
LOCAL is not supported in INSERT OVERWRITE DIRECTORY to data source(line 1, pos 0)

which was introduced in #18975, but this restriction is not needed, hence dropping the same.
Keep behaviour consistent for local and remote file-system in INSERT OVERWRITE DIRECTORY

Does this PR introduce any user-facing change?

Yes, after this change INSERT OVERWRITE LOCAL DIRECTORY will not throw exception

How was this patch tested?

Added UT

Hi, @ajithme . Could you update your PR description? It seems that you always put some content before the first section, but it's not an Apache Spark's recommendation. You need to move all content before What changes were proposed in this pull request? into somewhere below.

@dongjoon-hyun will ensure this, thanks for pointing out. I have updated the PR description

@ajithme, Can you double check how Hive works if other scheme are given? The current code seems always forcing to local scheme, e.g., hdfs:/a/b/c will becomes file:/a/b/c. Does Hive works in this way too?

Sure, i checked in Hive 2.3.5, it throws a exception if any other scheme is used apart form file:
success scenario
0: jdbc:hive2://QWE:10000/> insert overwrite local directory 'file:/tmp/sample' select 1; No rows affected (1.436 seconds) 0: jdbc:hive2://QWE:10000/> insert overwrite local directory '/tmp/sample' select 1; No rows affected (1.474 seconds)
fail scenario
Below is the stack from hive server on client
0: jdbc:hive2://QWE:10000/> insert overwrite local directory 'hdfs:///tmp/sample' select 1; WARNING: Hive-on-MR is deprecated in Hive 2 and may not be available in the future versions.

@HyukjinKwon Can i update the PR instead to follow Hive behavior i.e if a non local scheme is mentioned, the command fails.?

Updated PR to align behaviour with Hive
