--------------------------------------
Summary: CacheConfig details logged at Store open is not really
useful
Key: HBASE-24441
URL: https://issues.apache.org/jira/browse/HBASE-24441
Project: HBase
Issue Type: Improvement
Reporter: Anoop Sam John
Assignee: Anoop Sam John
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.
{code}
blockCache=org.apache.hadoop.hbase.io.hfile.CombinedBlockCache@7bc02941,
cacheDataOnRead=true, cacheDataOnWrite=true, cacheIndexesOnWrite=false,
cacheBloomsOnWrite=false, cacheEvictOnClose=false, cacheDataCompressed=false,
prefetchOnOpen=false
{code}
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.
