Review Comment:
To get the service name printed in log line in run method as we are not
overriding it in CompactionHouseKeeper.java
```
- LOG.info("Starting to run AcidHouseKeeperService.");
+ LOG.info("Starting to run {}", serviceName);
```
And reuse TxnHandler created already in AcidHouseKeeperService as we are
overriding cleanTheHouse method
```
void cleanTheHouse() {
if (isCompactorEnabled) {
performTask(getTxnHandler()::removeDuplicateCompletedTxnComponents,
"Cleaning duplicate COMPLETED_TXN_COMPONENTS entries");
performTask(getTxnHandler()::purgeCompactionHistory, "Cleaning
obsolete compaction history entries");
}
}
```
Please guide me if CompactionHouseKeeper needs to be completely decoupled
with AcidHouseKeeperService code wise by not implementing inheritance
