Scanning table using partial row key match returns unexpected results

[William Shen]

Hi there,

I am trying to scan using a partial match on the row key (derived from the
Phoenix primary key), however, hbase shell is returning results that do not
look like a match. Can someone help me understand why the following row
keys are considered a match and returned?

In addition, I am not sure how to interpret the values like \xF3^ and \x14'
that are suppose to be hex values...

hbase(main):001:0> import org.apache.hadoop.hbase.filter.CompareFilter

=> Java::OrgApacheHadoopHbaseFilter::CompareFilter

hbase(main):002:0> import org.apache.hadoop.hbase.filter.SubstringComparator

=> Java::OrgApacheHadoopHbaseFilter::SubstringComparator

hbase(main):003:0> import org.apache.hadoop.hbase.filter.RowFilter

=> Java::OrgApacheHadoopHbaseFilter::RowFilter

hbase(main):004:0> scan 'TEST_SCHEMA.TEST_TABLE', {COLUMNS => 'TG:_0',
LIMIT => 5, FILTER =>
RowFilter.new(CompareFilter::CompareOp.valueOf('EQUAL'),SubstringComparator.new("\x80\x00\x00\x00\x00\x00\x14\x27\x00\x07\x80\x00\x00\x00\x00\xC7\xE5\x87"))}

5 row(s) in 0.9430 seconds

Thanks in advance!
