Hemant Kumar updated HDDS-7885:
-------------------------------
Description: OFC cli fails to copy (was: Snapshot restore tests were
added as part of
[PR|https://github.com/apache/ozone/pull/4148/files#diff-2186b1fe62df6e3d2018bb4a9491761f79cff48e1ea81c3d50f85cd5f5bda7c7R256)]
and test to restore snapshot to another bucket fails sometime for *_Legacy
bucket_* layout with exception *_File Exists._* In the deep dive, it was found
that it is because of [PR|https://github.com/apache/ozone/pull/4038]. In the
PR, [seek operation was used on RocksDB
table|https://github.com/apache/ozone/pull/4038/files#diff-bde0dade7dd5ddda419499f4f999d25d40fcec1412e0ce809c36ffd1be473f22R1302-R1304]
which sometime returns non-null response and causes fake dir creation. It is
possible that RocksDB's seek operation uses bloom filter which doesn't
guarantee that key exists (false positive).
To fix this, we should add volume and bucket check
[here|https://github.com/apache/ozone/pull/4038/files#diff-bde0dade7dd5ddda419499f4f999d25d40fcec1412e0ce809c36ffd1be473f22R1306].
We may or may not need to iterate over the iterator. )
