Assignee: jeongmin kim (was: Jeongdae Kim)
> on hbase shell, 'delete/deleteall' for a columnfamily is not working
> --------------------------------------------------------------------
>
> Key: HBASE-26895
> URL: https://issues.apache.org/jira/browse/HBASE-26895
> Project: HBase
> Issue Type: Bug
> Components: shell
> Affects Versions: 3.0.0-alpha-2, 2.4.11
> Reporter: Jeongmin Kim
> Assignee: jeongmin kim
> Priority: Major
> Fix For: 2.5.0, 3.0.0-alpha-3, 2.4.12
>
>
> on hbase shell,
> 'delete' or 'deleteall' for the whole columnFamily is not working properly.
>
> {code:java}
> hbase(main):026:0* put 'test', 'r1', 'f:1', 'a'
> Took 0.0233 seconds
> hbase(main):029:0> delete 'test', 'r1', 'f'
> Took 0.0070 seconds
> hbase(main):030:0> get 'test', 'r1'
> COLUMN CELL
> f:1
> timestamp=1648114865022, value=a
> 1 row(s)
> hbase(main):038:0> deleteall 'test', 'r1', 'f'
> Took 0.0059 seconds
> hbase(main):039:0> get 'test', 'r1'
> COLUMN CELL
> f:1
> timestamp=1648114865022, value=a
> 1 row(s) {code}
>
> looking inside of hbase-shell,
> all delete/deleteall on hbase shell are converted to
> delete.addColumn/addColumns.
> thus, delete/deleteall request without columnQualifier converted to 'null'
> qualifier deletion. (since HBASE-15616, null columnQualifier is possible)
>
> {code:java}
> if column && all_version
> family, qualifier = parse_column_name(column)
> d.addColumns(family, qualifier, timestamp)
> elsif column && !all_version
> family, qualifier = parse_column_name(column)
> d.addColumn(family, qualifier, timestamp)
> end {code}
>
> According to the description of help 'deleteall' and HBASE-9549
> "Users of the shell, MapReduce, REST, and Thrift who wish to interact with
> an *entire column family must use "family"* instead of "family:" (notice the
> omitted ':'). Including the ':' will be interpreted as an interaction with
> the empty qualifier in the "family" column family."
>
> a column expression without ':' means whole family.
> so in these cases, it's deletion request for the columnFamily,
> and we should use addFamily/addFamilyVersion instead of addColumn/addColumns
> for deletion.
