@smdas Yes we are checking the size of the table within the table level directory. hdfs dfs -du -h -s /apps/hbase/data/mobdir/data/OBST/DOCUMENT_CONTENT/b8e8a5fee4eXX/cfDocContent. This is the table structure. create 'MOB:TEST', {NAME => 'cfDocContent', VERSIONS => '1', EVICT_BLOCKS_ON_CLOSE => 'false', NEW_VERSION_BEHAVIOR => 'false', KEEP_DELETED_CELLS => 'FALSE', CACHE_DATA_ON_WRITE => 'false', DATA_BLOCK_ENCODING => 'FAST_DIFF', TTL => 'FOREVER', MIN_VERSIONS => '0', REPLICATION_SCOPE => '0', BLOOMFILTER => 'ROW', CACHE_INDEX_ON_WRITE=> 'false', IN_MEMORY => 'false', CACHE_BLOOMS_ON_WRITE => 'false', PREFETCH_BLOCKS_ON_OPEN => 'false', IS_MOB => 'true', COMPRESSION => 'SNAPPY', BLOCKCACHE=> 'true', BLOCKSIZE => '65536'} , {NAME => 'cfMetadata', VERSIONS => '1', EVICT_BLOCKS_ON_CLOSE => 'false', NEW_VERSION_BEHAVIOR => 'false', KEEP_DELETED_CELLS => 'FALSE', CACHE_DATA_ON_WRITE=> 'false', DATA_BLOCK_ENCODING => 'FAST_DIFF', TTL => 'FOREVER', MIN_VERSIONS => '0', REPLICATION_SCOPE => '0', BLOOMFILTER => 'ROW', CACHE_INDEX_ON_WRITE => 'false', IN_MEMORY => 'false', CACHE_BLOOMS_ON_WRITE => 'false', PREFETCH_BLOCKS_ON_OPEN => 'false', COMPRESSION => 'SNAPPY', BLOCKCACHE => 'true', BLOCKSIZE => '65536'} Satya

Hi Team We have created the HBASE MOB tables and whenever we are deleting the data from hbase tables it's showing deleted from table but the hdfs size is not decreasing even after major compaction. Can anyone give any idea how to delete it completely so that there should be some space free at hdfs level. Regards, Satya

Hi, I am not able to permanently delete tombstone in Hbase. Tombstone markers are flushed for non-MOB column family but it is not flushed for the MOB column family. Any solution to delete the same so that we save some hdfs space. Regards, Satya
