Edward Yoon commented on HADOOP-2339: ------------------------------------- 'columnfamily', 'columnfamily:specified_qualifer' delete function is important thing. I'm not bothering to make a example. Also, I thought it should be work as inter-row wise partitioned sub structre parallelism. But, now shell is 0.0.1 version. Imagine the processing-speed:increment by row-count:increment 2d plots of scanner and mapreduce, start points of processing-speed dimension and slopes will be different. So, I thought the cross point find algorithm for the most faster automatical processing. 'Slow Performance' can't touch the grammar rules. > [Hbase Shell] Delete command with no WHERE clause > ------------------------------------------------- > > Key: HADOOP-2339 > URL: https://issues.apache.org/jira/browse/HADOOP-2339 > Project: Hadoop > Issue Type: Improvement > Components: contrib/hbase > Affects Versions: 0.16.0 > Reporter: Edward Yoon > Assignee: Edward Yoon > Fix For: 0.16.0 > > Attachments: 2339.patch, 2339_v02.patch, 2339_v03.patch, > 2339_v04.patch > > > using HbaseAdmin.deleteColumn() method. > {code} > DELETE column_name FROM table_name; > {code} -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
