-----------------------------------
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
Reporter: Yanjia Gary Li
Assignee: Vinoth Chandar

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?
