[Parameter] hbase.hstore.compaction.max.size [Default] Long.MAX_VALUE [Description] 
An StoreFile larger than this size will be excluded from compaction. The effect of raising hbase.hstore.compaction.max.size is fewer, larger StoreFiles that do not get compacted often. If you feel that compaction is happening too often without much benefit, you can try raising this value.
