>  *** Need logging in the scm log indicating a reconstruction was started for a particular container, etc, also a log entry indicating the reconstruction is completed. currently we only have this msg in the log:
> LOG.debug("Missing indexes detected for the container {}." +
> " The missing indexes are {}", id, missingIndexes);
> Assume same goes to over replication handling as well.
>  * 
>  ** 
>  *** Seems there was some out of sync when reporting number of processed containers from hdds.scm.container.replication.UnderReplicatedProcessor logging,
> Following were some sample log entries observed from scm log:
> :
> 2022-08-02 17:33:11,020 INFO org.apache.hadoop.hdds.scm.container.replication.UnderReplicatedProcessor: Processed 0 *under replicated containers, failed processing* 0
> 2022-08-02 17:33:41,021 INFO org.apache.hadoop.hdds.scm.container.replication.UnderReplicatedProcessor: Processed 0 *under replicated containers, failed processing* 0
> 2022-08-02 17:34:11,021 INFO org.apache.hadoop.hdds.scm.container.replication.UnderReplicatedProcessor: Processed 0 *under replicated containers, failed processing* 0
> 2022-08-02 17:34:41,021 INFO org.apache.hadoop.hdds.scm.container.replication.UnderReplicatedProcessor: Processed 0 *under replicated containers, failed processing* 0
> While the actual reconstruction was already done.
