Description

for (int i = 0; i < result.length; i++) {
      if (i >= fuzzyKeyMeta.length || fuzzyKeyMeta[i] == 1) {
        result[i] = row[offset + i];
        if (!order.isMax(row[i])) {
          // this is "non-fixed" position and is not at max value, hence we can increase it
          toInc = i;
        }
      }

See we take row bytes with out considering the row offset. The test cases are passing as we pass 0 offset row bytes. Change in the test will reveal the bug.

Came across this when I was working on HBASE-11425
