We have had issues when Java ORC reader cannot understand bloom filter produced by the C++ writer (which is caught by @stiga-huang). We may be safely assured when test cases report that the Java ORC reader can correctly read UNSTABLE_PRE_2_0 file created by the C++ ORC writer and vice versa. @dongjoon-hyun @stiga-huang @coderex2522 The [PR](https://github.com/apache/orc/pull/1062) has been tested using c++ ORC reader to read UNSTABLE_PRE_2_0 file created by the java ORC writer, so here only adds the test about java reader reads the file written by c++ writer. -- This is an automated message from the Apache Git Service.
