@sky76093016 I made it debug in HDDS-4356 because it was being printed
thousands of times during deletion. The idea of the jira was to investigate why
the below code was getting executed. On receiving ACK from all datanodes SCM
purges delete transaction from DB. If transaction is being resent after purge
then this log can be printed. I wanted to understand the scenario because there
might be a case where delete txn is being resent although it has been ACKed by
the datanodes.
```
if (block == null) {
if (LOG.isDebugEnabled()) {
// This can occur due to race condition between retry and old
// service task where old task removes the transaction and the
new
// task is resending
LOG.debug("Deleted TXID {} not found.", txID);
}
continue;
}
```
