ALTER TABLE test_rahul SET SERDEPROPERTIES ( "ignore.malformed.json" = "true");
Then It showing Null values for all the fields. Can someone Kindly Help me.

{
"buyer": {
"legalBusinessName": "test1 Company","organisationIdentifications": [{ "type": "abcd",
"identification": "test.bb@tesr"
},
{

}
]

@Rohan44 ,

Try creating your datafile with each JSON record in a single line, like so:

{"buyer":{"legalBusinessName":"test1 Company","organisationIdentifications":[{"type":"abcd","identification":"test.bb@tesr"},{"type":"TXID","identification":"12345678"}]},"supplier":{"legalBusinessName":"test Company","organisationIdentifications":[{"type":"abcd","identification":"test28@test"}]},"paymentRecommendationId":"1234-5678-9876-2212-123456","excludedRemittanceInformation":[],"recommendedPaymentInstructions":[{"executionDate":"2022-06-12","paymentMethod":"aaaa","remittanceInformation":{"structured":[{"referredDocumentInformation":[{"type":"xxx","number":"12341234","relatedDate":"2022-06-12","paymentDueDate":"2022-06-12","referredDocumentAmount":{"remittedAmount":2600.5,"duePayableAmount":3000}}]}]}}]}

Thanks a lot @araujo It Worked.
is there any option to handle this with multiline also.As we are getting this files from source in multiline.

@Rohan44 ,

Unfortunately, I don't think there's a way to do that.

What are you using to write the files to HDFS?

Cheers,
