[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=16428474#comment-16428474 ]
Steve Loughran commented on HADOOP-15370:
-----------------------------------------
Slightly better with the debug trace included
{code}
018-04-06 16:35:23,048 [main] DEBUG s3a.S3AFileSystem (S3AFileSystem.java:innerDelete(1760)) - Delete path s3a://hwdev-steve-new/ - recursive true
2018-04-06 16:35:23,048 [main] DEBUG s3a.S3AFileSystem (S3AFileSystem.java:innerDelete(1765)) - delete: Path is a directory: s3a://hwdev-steve-new/
2018-04-06 16:35:23,048 [main] INFO s3a.S3AFileSystem (S3AFileSystem.java:rejectRootDirectoryDelete(1837)) - s3a delete the hwdev-steve-new root directory of true
rm: `s3a://hwdev-steve-new/': Input/output error
2018-04-06 16:35:23,050 [pool-2-thread-1] DEBUG s3a.S3AFileSystem (S3AFileSystem.java:close(2492)) - Filesystem s3a://hwdev-steve-new is closed

Proposed:
# improve info message. downgrade?
# log @ error before throwing the exception

> Key: HADOOP-15370
> URL: https://issues.apache.org/jira/browse/HADOOP-15370
> Project: Hadoop Common
> Issue Type: Sub-task
> Components: fs/s3
> Affects Versions: 3.1.0
> Reporter: Steve Loughran
> Priority: Trivial
>
> 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}
> 2018-04-06 16:35:23,048 [main] INFO s3a.S3AFileSystem (S3AFileSystem.java:rejectRootDirectoryDelete(1837)) - s3a delete the hwdev-steve-new root directory of true
> rm: `s3a://hwdev-steve-new/': Input/output error
> 2018-04-06 16:35:23,050 [pool-2-thread-1] DEBUG s3a.S3AFileSystem
> {code}
> the single log message doesn't parse, and the error message raised is lost by the FS -rm CLI command (why?)
