Is hbase call delete request for old hfile(storeFile) file if minor/major compaction happen for them and generate new hfile and store it in hdfs.
for minor compaction how it will get size of every hfile. lets we have 20 no. of hfiles for a CF and minor compaction wants to perform. Will it download all hfile and decide compaction have to do or not. Or it have in-memory hfile's size information for all hfile.
