Jeffrey Zhong updated HBASE-10366:
----------------------------------
Description:
HBASE-6429 combines both filterRow & filterRow(List<KeyValue> kvs) functions in
Filter.
While 0.94 code or older, it may not implement hasFilterRow as HBase-6429
expected because 0.94(old) hasFilterRow only returns true when
filterRow(List<KeyValue> kvs) is overridden not the filterRow(). Therefore, the
filterRow() will be skipped.
Since we don't ask 0.94 users to update their existing filter code, the issue
will cause scan returns unexpected keyvalues and break the backward
compatibility.
