Hi Team,
while deploying feature into feature store getting error like below ,current
environment is solr 6 with branch_6x commit of LTR
BAN7265:solr-6.3.0-setup athondur$ curl -XPUT

./Users/athondur/Desktop/solr_6.3/solr-6.3.0-setup/contrib/ltr/example/techproducts-features.json"
-H 'Content-type:application/json'
Warning: Couldn't read data from file "
Warning: ./Users/athondur/Desktop/solr_6.3/solr-6.3.0-setup/contrib/ltr/example

> Integrate Learning to Rank into Solr
> ------------------------------------
>
> Key: SOLR-8542
> URL: https://issues.apache.org/jira/browse/SOLR-8542
> Project: Solr
> Issue Type: New Feature
> Reporter: Joshua Pantony
> Assignee: Christine Poerschke
> Priority: Minor
> Attachments: SOLR-8542-branch_5x.patch, SOLR-8542-trunk.patch,
> SOLR-8542.patch
>
>
> This is a ticket to integrate learning to rank machine learning models into
> Solr. Solr Learning to Rank (LTR) provides a way for you to extract features
> directly inside Solr for use in training a machine learned model. You can
> then deploy that model to Solr and use it to rerank your top X search
> results. This concept was previously [presented by the authors at Lucene/Solr
> Revolution
> 2015|http://www.slideshare.net/lucidworks/learning-to-rank-in-solr-presented-by-michael-nilsson-diego-ceccarelli-bloomberg-lp].
> [Read through the
> README|https://github.com/bloomberg/lucene-solr/tree/master-ltr-plugin-release/solr/contrib/ltr]
> for a tutorial on using the plugin, in addition to how to train your own
> external model.
