>
> *Problem Statement* - Hive Compaction Initiator not initiating compaction
> for few tables.
> Every Initiator cycle hits exactly 1000 candidates (COMPACTOR_FETCH_SIZE
> limit) and ignores the rest on the next cycle
> In findPotentialCompactions, the condition TC.CTC_TIMESTAMP >=
> CURRENT_TIMESTAMP - INTERVAL 300 SECOND, returns rows where CTC_TIMESTAMP is
> within the last 300 seconds, i.e., the last 5 minutes.
> The next cycle doesn't pick this table due to the above condition hence it
> remains in the table itself.
