> Hi Team,
> I'm using bulk insert option to load close to 2 TB data. The process is taking near by 2 hours to get completed. While looking at the job log, it is identified that [sortBy at GlobalSortPartitioner.java:41|https://gdlcuspc1a3-6.us-central1.us.walmart.net:18481/history/application_1614298633248_1444/1/jobs/job?id=1] is running twice. 
> It is getting triggered at 1 stage. *refer this screenshot ->[^1st.png]*.
> Second time it is getting trigged from  *HoodieSparkSqlWriter.scala:433* *[count at HoodieSparkSqlWriter.scala:433|https://gdlcuspc1a3-6.us-central1.us.walmart.net:18481/history/application_1614298633248_1444/1/jobs/job?id=2]*   step.
> In both cases, same number of job got triggered and running time is close to each other. *Refer this screenshot* -> [^2nd.png]
> Is there any way to run only one time so that data can be loaded faster or it is expected behaviour.
