Neil Joshi commented on HDDS-7885:
----------------------------------
In addition to the tmp file with underscore problem with the -cp command when
the dest bucket needs to be created the in the copy is another problem,
{code:java}
bash-4.2$ ozone fs -cp -d ofs://om/vol1/bucket1/key1 ofs://om/vol1/bucket2
cp: Cannot create file under root or volume.{code}
We are currently unable to create the destination bucket in the -cp command
process. [~sumitagrawl] this looks to be in the ozone filesystem (basic, basic
rooted).

> Key: HDDS-7885

> Project: Apache Ozone
> Issue Type: Bug
> Components: Ozone Filesystem
> Reporter: Hemant Kumar
> Priority: Major
>
> OFS cli fails to copy keys from source bucket to destination bucket if
> destination bucket doesn't exist with exception message {*}cp: Bucket or
> Volume name has an unsupported character : _{*}.
> In actual, CLI tries to create bucket when it doesn't exist with ._ COPYING _
> extension
> [code|https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/fs/shell/CommandWithDestination.java#L425].
> We need to update Ozone to be compatible with Hadoop and allow copy if bucket
> doesn't exist.
> Step to reproduce: Similar to
> [test|https://github.com/apache/ozone/blob/HDDS-6517-Snapshot/hadoop-ozone/integration-test/src/test/java/org/apache/hadoop/ozone/om/snapshot/TestOzoneSnapshotRestore.java#L196]
> * Create a source volume: *vol1* and bucket: *bucket1*
> * Add key: *key1* to */vol1/bucket1*
> * Run -cp command using OFS CLI with source path: */vol1/bucket1/key1* and
> destination path: {*}/vol1/bucket2{*}.
> * It would fail with exception message {*}cp: Bucket or Volume name has an
> unsupported character : _{*}.
> This is discovered while debugging HDDS-7861, a snapshot test. During
> debugging, we passed the wrong bucket and test failed with above exception.
