Example 1 with RandomRowFilter

use of org.apache.hadoop.hbase.filter.RandomRowFilter in project hbase by apache.

the class TestPartialResultsFromClientSide method testNoPartialResultsWhenRowFilterPresent.

/**
   * When a scan has a filter where {@link org.apache.hadoop.hbase.filter.Filter#hasFilterRow()} is
   * true, the scanner should not return partial results. The scanner cannot return partial results
   * because the entire row needs to be read for the include/exclude decision to be made
