--------------------------------
Assignee: Peter Lee
> SnapshotDiffReportOzone#fromProtobuf empty token handling
> ----------------------------------------------------------
>
> Key: HDDS-12823
> URL: https://issues.apache.org/jira/browse/HDDS-12823
> Project: Apache Ozone
> Issue Type: Sub-task
> Reporter: Ivan Andika
> Assignee: Peter Lee
> Priority: Minor
>
> 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 in SnapshotDiffReportOzone#fromProtobuf.
