> I am using the manual build master after [https://github.com/apache/incubator-hudi/commit/36b3b6f5dd913d3f1c9aa116aff8daf6540fed65] commit.
> I am seeing 3 million tasks when the Hudi Spark job writing the files into HDFS.
> I am seeing a huge amount of 0 byte files being written into .hoodie/.temp/ folder in my HDFS. In the Spark UI, each task only writes less than 10 records in
> {code:java}
> count at HoodieSparkSqlWriter{code}
> All the stages before this seems normal. Any idea what happened here?
