Examples: 27 28 hbase> deleteall 'ns1:t1', 'r1' 29 hbase> deleteall 't1', 'r1' 30 hbase> deleteall 't1', 'r1', 'c1' 31 hbase> deleteall 't1', 'r1', 'c1', ts1 32 hbase> deleteall 't1', 'r1', 'c1', ts1, {VISIBILITY=>'PRIVATE|SECRET'} 33 34The same commands also can be run on a table reference. Suppose you had a reference 35t to table 't1', the corresponding command would be: 36 37 hbase> t.deleteall 'r1' 38 hbase> t.deleteall 'r1', 'c1' 39 hbase> t.deleteall 'r1', 'c1', ts1 40 hbase> t.deleteall 'r1', 'c1', ts1, {VISIBILITY=>'PRIVATE|SECRET'} 41EOF 42 end 43 44 def command(table, row, column = nil, 45 timestamp = org.apache.hadoop.hbase.HConstants::LATEST_TIMESTAMP, args = {}) 46 deleteall(table(table), row, column, timestamp, args) 47 end 48 49 def deleteall(table, row, column = nil, 50 timestamp = org.apache.hadoop.hbase.HConstants::LATEST_TIMESTAMP, args = {}) 51 format_simple_command do 52 table._deleteall_internal(row, column, timestamp, args) 53 end 54 end 55 end 56 end 57end 58 59#Add the method table.deleteall that calls deleteall.deleteall 60::Hbase::Table.add_shell_command("deleteall") 61
