             Summary: Recon's keyContainerTable doesn't get cleaned up after key deletes
                 Key: HDDS-9662
                 URL: https://issues.apache.org/jira/browse/HDDS-9662
             Project: Apache Ozone

          Components: Ozone Recon
            Reporter: Christos Bisias
            Assignee: Christos Bisias


After key deletes and syncing Recon with OM, *keyContainerTable* isn't updated and all the entries are still there.

This can be tested manually following the steps below.

from project root

 
{code:java}
> cd hadoop-ozone/dist/target/ozone-1.4.0-SNAPSHOT/compose/ozone{code}
start docker env and connect to Recon

 

 
{code:java}
> docker-compose up --scale datanode=3 -d
> docker-compose exec recon bash {code}
create keys

 

 
{code:java}
bash-4.2$ ozone freon ockg -t 10 -n 10 
...
...
Total execution time (sec): 2 
Failures: 0 
Successful executions: 10 {code}
delete all the keys

 

 
{code:java}
bash-4.2$ ozone fs -ls /vol1/bucket1 Found 1 items drwxrwxrwx   - hadoop hadoop          0 2023-11-09 13:04 /vol1/bucket1/ye6rtz4g0t

bash-4.2$ ozone fs -rm -r -skipTrash /vol1/bucket1/ye6rtz4g0t
