             Summary: BloomContext#sanityCheck may failed when use ROWPREFIX_DELIMITED bloom filter
                 Key: HBASE-21922
                 URL: https://issues.apache.org/jira/browse/HBASE-21922
             Project: HBase
          Issue Type: Bug
            Reporter: Guanghao Zhang


Assume we use '5' as the delimiter, there are rowkeys
{code:java}
12345xxx
1235xxxx{code}
When use ROWPREFIX_DELIMITED bloom filter, the rowkey write to bloom filter are
{code:java}
1234
123{code}
Then BloomContext#sanityCheck will failed.
{code:java}
private void sanityCheck(Cell cell) throws IOException {
  if (this.getLastCell() != null) {
    LOG.debug("Current cell " + cell + ", prevCell = " + this.getLastCell());
    if (comparator.compare(cell, this.getLastCell()) <= 0) {
      throw new IOException("Added a key not lexically larger than" + " previous. Current cell = "
          + cell + ", prevCell = " + this.getLastCell());
    }
  }
}
{code}
