[jira] [Commented] (HADOOP-15370) S3A log message on rm
s3a://bucket/ not intuitive
[ https://issues.apache.org/jira/browse/HADOOP-15370?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16694952#comment-16694952 ]
Gabor Bota commented on HADOOP-15370:
-------------------------------------
Created an initial patch based on the idea that org.apache.hadoop.fs.s3a.S3AFileSystem#innerDelete returns what returned from org.apache.hadoop.fs.s3a.S3AFileSystem#rejectRootDirectoryDelete, and the same is returned to org.apache.hadoop.fs.s3a.S3AFileSystem#delete which ultimately returned to org.apache.hadoop.fs.shell.Delete.Rm#processPath and we have the {{PathIOException}} which outputs the Input/output error.
Based on that, I found that the best places to add the messages are the ones I used.

> when you try to delete the root of a bucket from command line, e.g. {{hadoop fs -rm -r -skipTrash s3a://hwdev-steve-new/}}, the output isn't that useful
> {code}

> the single log message doesn't parse, and the error message raised is lost by the FS -rm CLI command (why?)
