HangyuanLiu commented on issue #2812: Fix parquet arrow read batch bug
URL: https://github.com/apache/incubator-doris/pull/2812#issuecomment-576143120
 
 
   The original code was to determine the number of rows in the batch based on 
the number of rows in the parquet RowGroup.
    It could be a batch as many as a rowgroup in last arrow lib?
   But now it's a batch take 65535 lines , so when parquet row  greater than 
65535,be may crash
