Hi,

My goal is to create a pipeline that does the following:

1)Ingest data from mysql to a temporary location in hdfs in avro format

2)Convert avro files to parquetwith a map reduce executor as explained here https://streamsets.com/documentation/...

3) Validate with a query if the number of ingested rows is correct and if validation is ok then

4) Ingest data from mysql to a permanent location in hdfs again in parquet

The problem is that in step 2 I don't know when all files are converted in parquet in order to continue to step 3, since streamsets can't monitor mapreduce jobs.

Could you help me fix this problem? Is there an alternative way to send data in HDFS in parquet format?

Thank you!
