The infaoptimize argument defines whether you want to disable the performance optimization of Sqoop pass-through mappings on the Spark engine.
When you run a Sqoop pass-through mapping on the Spark engine, the Data Integration Service optimizes mapping performance in the following scenarios:
  • You read data from a Sqoop source and write data to a Hive target that uses the Text format.
  • You read data from a Sqoop source and write data to an HDFS target that uses the Flat, Avro, or Parquet format.
If you want to disable the performance optimization, set the --infaoptimize argument to false. For example, if you see data type issues after you run an optimized Sqoop mapping, you can disable the performance optimization.
Use the following syntax:
--infaoptimize false


We’d like to hear from you!
