Hi all,
I'm new to Hudi and looking to leverage Delta Streamer for JSON sources that
is available in my s3 bucket.
Below is the code snippet that i'm using to execute the same
Source File(Json Format)
{"empno":"8006","ename":"stuart","job":"salesman","hiredate":"2020-01-01
00:00:00"}
Code
spark-submit --class
org.apache.hudi.utilities.deltastreamer.HoodieDeltaStreamer `ls
/usr/lib/hudi/hudi-utilities-bundle_2.11-0.5.2-incubating.jar`
--table-type COPY_ON_WRITE
--source-class org.apache.hudi.utilities.sources.JsonDFSSource
--target-base-path s3://gowtham_km/hudi/target> --target-table emp
--hoodie-conf
hoodie.datasource.write.recordkey.field=empno,hoodie.deltastreamer.source.dfs.root=s3://gowtham_km/hudi/source>
--transformer-class org.apache.hudi.utilities.transform.AWSDmsTransformer
--payload-class org.apache.hudi.payload.AWSDmsAvroPayload
--props
file:/usr/lib/hudi/hudi_utilities/delta-streamer-config/dfs-source.properties
--schemaprovider-class org.apache.hudi.utilities.schema.SchemaProvider

To start with learning would like to load the json file into target table
and then later will add continuous option to load the new files into target
table automatically.
