Summary: Some snapshotDiff command returns empty result when
multiple snapshots diff commands run concurrently
Key: HDDS-8303
URL: https://issues.apache.org/jira/browse/HDDS-8303
Project: Apache Ozone
Issue Type: Bug
Reporter: Dave Teng
Some snapshotDiff command returns empty result when multiple snapshots diff
commands run concurrently.
I tried to run 50 concurrent snapshotDiff command against 50 different set of
snapshots which were different (They all contained different key-operations
differences between snapshots. So these key namespaces between snapshots are
all different.). Only two processes returns the snapshot diff reports, the
other processes returned empty response. The expected result should not be
empty unless two snapshots contains no difference in key namespace. However
each snapshotDiff command I run here used different snapshots which contains
different keys namespace, empty response should not happen in theory.
