Subject Re: HBase tables snippet
Date Sun, 21 Aug 2011 17:33:07 GMT
Hi Vincent,

If you are able to provide some criteria for selecting the
rows(rowkey/composite rowkey/column) etc, you can try using Crux at
https://github.com/sonalgoyal/crux. With Crux, you can  select specific data
in HBase columns by defining filters and view the data in a tabular/chart

Let me know if you need any help.

Best Regards,
