> @guiyanakuang, I just tested your Patch on none-1.orc, looks like it
doesn't work. Could you help to double-check it?
@wbo4958 In the file nones-1.orc, index.getNumberOfValues() returns 0
instead of the actual 3 rows of data. So it doesn't work, we need to make sure
the statistics are consistent with the actual.
It is important to note that none-1.orc contains statistics.
You can write an orc file without the rowIndex statistics for comparison by
doing the following
```java
OrcFile.createWriter(new Path(".orc"),
OrcFile.writerOptions(conf)
.rowIndexStride(0) // Set
rowIndexStride to 0 to avoid writing rowIndex
.setSchema(schema));
```
