However, during the debugging process, we found it quite difficult to track where the file is being moved when we failed to do so. moveToTrash() function does not print the trash root path. Thus, I added this change when we failed. -- This is an automated message from the Apache Git Service.

ViewFileSystem is assuming the path that it > receives is a viewFS path, but not a target FS path.

In this case, it is incorrect to return the > trash root as viewfs:/user/foo, as it will be resolved to the abfs mount > point, instead of the fallback hdfs. > -- This message was sent by Atlassian Jira (v8.20.1#820001) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
