I wish I could, but currently prohibited. However, I can point you to some
very good Java libraries:
The CSV parser supplied by the Apache project works well:
https://commons.apache.org/proper/commons-csv/apidocs/org/apache/commons/csv/CSVParser.html
You can override the delimiter using the static CSVFormat newFormat(char
delimiter) method which creates a new CSV format with the specified
delimiter:
https://commons.apache.org/proper/commons-csv/apidocs/org/apache/commons/csv/CSVFormat.html
Then use the XContentBuilder cb = jsonBuilder() method call to create a
content builder to convert your records to single-line JSON.
For example, the action and meta data object I use is based on the
following ENUM and toString method to emit as JSON. I've left out the parst
that I use in other custom libraries that allow Java code to easily set up
this information, and also to set this from a search response or a
get-by-id response:
public enum OpType
{
CREATE,
INDEX,
DELETE
}
@Override
public String toString()
{
try
{
XContentBuilder cb = jsonBuilder();
cb.startObject();
cb.field(opType.toString().toLowerCase());
cb.startObject();
cb.field("_index", index);
cb.field("_type", type);
if (id != null)
cb.field("_id", id);
if (version > 0)
{
cb.field("_version", version);
if (versionType == VersionType.EXTERNAL)
cb.field("_version_type", "external");
}
if (ttl != null)
cb.field("_ttl", ttl);
cb.endObject();
cb.endObject();
return cb.string();
}
catch (IOException e)
{
return ("null");
}
}
/* Operation type (action): "create" or "index" or "delete" */
private OpType opType = OpType.INDEX;
/* Metadata that this object supports */
private String index = null;
private String type = null;
private String id = null;
private long version = 0;
private VersionType versionType = VersionType.INTERNAL;
private TimeValue ttl = null;
And the actual data line that would follow is similarly constructed using
the content builder.
I wish I could help you more.

Thank you brian. Let me change it accodingly as per your suggestion.
Could it possible to share the bulk load client and csv to json converter?
