Subject Re: HBase Delete - based on non-rowkey columns
Date Wed, 06 Nov 2013 09:20:03 GMT
1)   In HBASE, is it possible to delete a row  based on a column name &
 value.   The column name should not be a row key, because in this scenario
we cannot delete    based on the row key.

YES, you can with a Filter.

2) Is it possible to delete a row in HBase table , based on the partial row
key.

YES, you can with a RegexStringComparator based Filter, here is an example:

Filter rf = new RowFilter(CompareFilter.CompareOp.EQUAL,
newRegexStringComparator(
"(.*" + platform + "#" + groupDate

                + ")"));


Cheers

Ramon
