Hi
We have created the table with the value of KEEP_DELETED_CELLS =false .
So ideally it should be delete the data from HDFS also and snapshot is also
not enable.
We are just creating the tables and putting the data and after that we are
deleting the data of that column family.
The no of count has reduced in hbase table but when we have checked the
hdfs dircetory for the hbase the size is same even we ran major compaction
also but no impact on hdfs size.
Below is the query which we are using
create 'OBST: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 =>

CACHE_BLOOMS_ON_WRITE => 'false', PREFETCH_BLOCKS_ON_OPEN => 'false',
COMPRESSION => 'SNAPPY', BLOCKCACHE => 'true', BLOCKSIZE => '65536'}
put 'OBST:TEST','Test101','cfDocContent:doc','row101'
put 'OBST:TEST','Test102','cfDocContent:doc','row102'
put 'OBST:TEST','Test103','cfDocContent:doc','row103'

put 'OBST:TEST','Test107','cfMetadata:doc','row107'
put 'OBST:TEST','Test108','cfMetadata:doc','row108'

delete 'OBST:TEST','Test103','cfDocContent:doc'
delete 'OBST:TEST','Test106','cfMetadata:doc'
delete 'OBST:TEST','Test107','cfMetadata:doc'
delete 'OBST:TEST','Test108','cfMetadata:doc'
flush 'OBST:TEST'
compact 'OBST:TEST'
major_compact 'OBST:TEST', 'cfDocContent', 'MOB'
major_compact 'OBST:TEST
*hbase(main):185:0>* scan 'OBST:TEST', {RAW => TRUE}
*ROW COLUMN+CELL*
*Test101 column=cfDocContent:doc, timestamp=1608282551809, type=Delete*
*Test102 column=cfDocContent:doc, timestamp=1608282551824, type=Delete*
*Test103 column=cfDocContent:doc, timestamp=1608282551838, type=Delete*
*Even the tombstone mark is also there and the size of hdfs directory
didn't reduce. It's not moving in to trash also.*
*Let me know if you need some additional information*
Hbase version is 2.0.2.3.1.4.0-315

Satya
