Hemant Kumar created HDDS-7910:
----------------------------------
Summary: OFS CLI should copy the file to /tmp dir while copying to
bucket and destination bucket doesn't exist or direct write is disbled.
Key: HDDS-7910
URL: https://issues.apache.org/jira/browse/HDDS-7910
Project: Apache Ozone
Issue Type: Bug
Components: Ozone Filesystem
Reporter: Hemant Kumar
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.
