Just my two cents... The HBase shell has some components that are extremely valuable to the core of HBase. In particular, administrative functions such as creating/deleting/modifying tables and the ability to do simple queries from the command line.
On the other hand, some of the proposed extensions are either extraneous or outside the scope of the HBase core. For example a socket server to the shell seems extraneous given that HBase has a REST interface. High volume updates or queries might better be handled by providing native language bindings for HBase. One mechanism that has been proposed for this is to use Thrift to communicate between clients and the HBase servers. Other extensions such as Matrix operations, RDF, and Relation-Algebra might better be packaged in a separate jar so they could be utilized in map/reduce jobs. Additionally, if they were generalized so that they could accept inputs from sources other than HBase, such as SequenceFiles (for example) it would be possible to apply these operations to non-HBase map/reduce jobs. In the shell, the ability to create and submit a map/reduce job using these operations might also be useful. --- Jim Kellerman, Senior Engineer; Powerset > -----Original Message----- > From: edward yoon [mailto:[EMAIL PROTECTED] > Sent: Friday, December 07, 2007 9:36 PM > To: hadoop-dev@lucene.apache.org > Subject: RE: [VOTE][PLAN] Graduate Hbase Shell as a contrib project > > > Ok stack, The effort to questionnaire rebuild has just begun. > > ------------------------------ > > B.
