Which column causes issue in MapperParsingException

[ruvikal]

I came across this error

Caused by: org.elasticsearch.hadoop.rest.EsHadoopInvalidRequest: Found unrecoverable error [Bad Request(400) - [MapperParsingException[failed to parse]; nested: NumberFormatException[For input string: "NULL"]; ]]; Bailing out..

when loading data into elasticsearch from hive using the elasticsearch-hadoop-2.0.2.jar.
The error doesn't reveal which column is causing the issue. It would be nice to have such information in the error.

I'm closing this issue as there's not much a client (such as ES-Hadoop) can do. The error above is thrown by Elasticsearch about a mapping error between the data sent and the mapping inside ES. The error is returned as is to the user for full diagnostic; the client can't do much about it.
