Hi team ,

I am trying to use a tHmapinput component in a big data spark jobs to read a HL7 file.\

Only the mapper works fine(data mapper perspective), but when i connect to a spark job it doesn't give any results nor throw an exception,but the job runs to success with no results.

thank you ,

lily

Hello,

When using it in a Spark environment, this component is used with a tHDFSConfiguration component which defines the connection to the HDFS storage.

Please see more information here
