Hyukjin Kwon reassigned SPARK-46633: ------------------------------------ Assignee: Ivan Sadikov > Reading a non-empty Avro file with empty blocks returns 0 records > ----------------------------------------------------------------- > > Key: SPARK-46633 > URL: https://issues.apache.org/jira/browse/SPARK-46633 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 3.5.0, 4.0.0 > Reporter: Ivan Sadikov > Assignee: Ivan Sadikov > Priority: Major > Labels: pull-request-available > > When an Avro file contains empty blocks, Spark returns 0 records while > "fastavro" and "avro-python-3" both read the file correctly and return > records. > > This is due to the way Spark handles empty blocks (or does not handle). Call > to `hasNext` loads the next block and if that block is empty, it returns > false. But instead of exiting the loop, we need to probe the next block until > sync point is reached. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
