如何使用HBase Shell从HBase获取以特定值结尾的行

Question

How to fetch rows that ends with specific value in Hbase? For example I have below rowskeys in my table

   D1|V1
   D2|V1
   D3|V2
   D4|V1

Now I need all rows that ends with V1. In this example I should get D1,D2 and D4.

Can some one suggest how to achieve this in Hbase

Answer 1

I achieved it using below:

   import org.apache.hadoop.hbase.filter.CompareFilter
   import org.apache.hadoop.hbase.filter.SubstringComparator
   scan 'tableName', {FILTER => org.apache.hadoop.hbase.filter.RowFilter.new(CompareFilter::CompareOp.valueOf('EQUAL'),SubstringComparator.new("SubString"))}

and through Java

    FilterList filterList = new FilterList(Operator.MUST_PASS_ONE);
    List<String> referenceList = new ArrayList<String>();
    ResultScanner results = null;
    String substr= "V1";
    RowFilter rowfilter = new RowFilter(CompareOp.EQUAL, new SubstringComparator(substr));
    filterList.addFilter(rowfilter);
    Scan prefilterScan = new Scan();
    prefilterScan.setFilter(filterList);
