             Summary: [DEBUGGING] Huge amount of tasks when writing files into 
HDFS
                 Key: HUDI-494
                 URL: https://issues.apache.org/jira/browse/HUDI-494
             Project: Apache Hudi (incubating)
          Issue Type: Test

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?
