Sahil Takiar reopened IMPALA-8950:
----------------------------------
This is breaking some S3 tests, so re-opening.
> Add -d and -f option to copyFromLocal and re-enable disabled S3 tests
> ---------------------------------------------------------------------
>
> Key: IMPALA-8950
> URL: https://issues.apache.org/jira/browse/IMPALA-8950
> Project: IMPALA
> Issue Type: Test
> Reporter: Sahil Takiar
> Assignee: Sahil Takiar
> Priority: Major
> Fix For: Impala 3.4.0
>
>
> The {{-d}} option for {{hdfs dfs -copyFromLocal}} "Skip[s] creation of
> temporary file with the suffix ._COPYING_". The {{-f}} option "Overwrites the
> destination if it already exists".
> By using the {{-d}} option, copies to S3 avoid the additional overhead of
> copying data to a tmp file and then renaming the file. The {{-f}} option
> overwrites the file if it exists, which should be safe since tests should be
> writing to unique directories anyway. With HADOOP-16490,
> {{create(overwrite=true)}} avoids issuing a HEAD request on the path, which
> prevents any cached 404s on the S3 key.
> After these changes, the tests disabled by IMPALA-8189 can be re-enabled.
