> Analysis from [~anoop.hbase]:
> Checking the related code. There seems no issue.. We are not going
> to even fail reading the bloom. In 2.0 code base we expect the
> comparator class name to be null. But in 1.x we write old KV based
> Raw Bytes comparator class name. So reading that back, we will return
> class name as null and we get NPE it looks like.
> {code:java}
> else if
> (comparatorClassName.equals("org.apache.hadoop.hbase.KeyValue$RawBytesComparator")
> ||
> comparatorClassName.equals("org.apache.hadoop.hbase.util.Bytes$ByteArrayComparator"))
> {
> // When the comparator to be used is Bytes.BYTES_RAWCOMPARATOR,
> we just return null from here
> // Bytes.BYTES_RAWCOMPARATOR is not a CellComparator
> comparatorKlass = null;
> }
> {code}
> We can better do a null check before trying the comparator class
> instantiation so that we can avoid this scary error logs
