Ingest External thetasketch.bin to druid

Hi,

I have created thetasketch.bin to outside druid. Which is in my local directory.

Now I want to run index_parallel task from my local directory.

Local directory having tsv, file consists of following headers – dimension_1,dimension_2,metrics_1

During indexer task submit, I want to use isInputThetaSketch: true for metrics_1 field.

Query is in metrics_1 how I can write thetasketch object ?? should I have to pass thetasketch.bin filename ??
