Ingesting Parquet file gives UTF-8 error [Druid 0.12.0]

I've a AWS Glue generated Parquet file. I've installed Parquet and Avro extensions (tried with 0.12.0 and 0.12.1 both) and I get following error in each case

$ >curl -X 'POST' -H 'Content-Type:application/json' -d @quickstart/master.parquet localhost:8090/druid/indexer/v1/task

}

Any clue?

Solution

1.you should modify this command (change master.parquet to master.json ): $ >curl -X 'POST' -H 'Content-Type:application/json' -d @quickstart/master.parquet
2. in the json config file ,the "paths" should be write the data path
