beliefer commented on issue #23841: [SPARK-26936][SQL] Fix bug of insert overwrite local dir can not create temporary path in local staging directory URL: https://github.com/apache/spark/pull/23841#issuecomment-477856708 > After the change, `qualifiedPath` is constructed as: > `val qualifiedPath = FileUtils.makeQualified(targetPath, hadoopConf)` > Before it was qualified w.r.t. the local file system. > Doesn't this become a path on the distributed file system? that's the point of this change. But, if `targetPath` is "/tmp/foo", this assumes it's valid to use "/tmp/foo" on the distributed storage. That doesn't seem technically right. Am I missing something so far? If `targetPath` is "/tmp/foo", and assumes it's valid to use `tmpPath` "hdfs://tmp/foo" on the distributed storage. But the original code uses the "file:/tmp/foo" as `tmpPath`.
