represents decimal
Anuradha Bhan created SPARK-36589:
-------------------------------------
Summary: Creating a value in json which represents decimal
Key: SPARK-36589
URL: https://issues.apache.org/jira/browse/SPARK-36589
Project: Spark
Issue Type: Question
Components: Spark Core
Affects Versions: 3.1.2
Reporter: Anuradha Bhan
Hi,
I have a json which have some decimal values . This json is read by Spark like the following :
Dataset<Row> df = spark.read().format("json").option("multiline","true").load("/home/user/work/Parquet/output.json");
The schema generated by this (df.printschema) shows the decimal value as double and not decimal .
My requirement is that it should read the value as decimal only.
Now to do this, I want change the value in json (while creating the json) in such a way or format that spark reads it as decimal only .
And in this conversion method, I need to apply the precision and scale also
Please let me know how this can be done
Thanks and Regards
Anuradha
