Description

CacheConfig constructor is logging 'this' object at INFO level. This log comes during Store open(As CacheConfig instance for that store is created). As the log is at CacheConfig only, we don't get to know this is for which region:store. So not really useful log.

blockCache=org.apache.hadoop.hbase.io.hfile.CombinedBlockCache@7bc02941, cacheDataOnRead=true, cacheDataOnWrite=true, cacheIndexesOnWrite=false, cacheBloomsOnWrite=false, cacheEvictOnClose=false, cacheDataCompressed=false, prefetchOnOpen=false

Also during every compaction also this logs keeps coming. This is because during compaction we create new CacheConfig based on the HStore level CacheConfig object. We can avoid this log with every compaction happening.
