Ivan Andika updated HDDS-12823:
-------------------------------
Description:
Currently in SnapshotDiffReportOzone#fromProtobuf,
SnapshotDiffReportProto#getToken when initializing SnapshotDiffReportOzone is
called regardless whether the token is specified
(SnapshotDiffReportProto#hasToken). This causes token to be an empty string due
to the protobuf default value.
If a client wants to list all the snapdiff entries and only check whether the
token is not null as the termination condition, it will cause the snapdiff list
to get stuck infinite loop. It's better to set the SnapshotDiffReportOzone
token to null.
