Sahil Takiar created IMPALA-8950: ------------------------------------ Summary: 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
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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
