Subject Lucene, Spark, HDFS question
Date Tue, 13 Mar 2018 23:31:30 GMT

*Background*: My team is running a machine learning pipeline, and part of
the pipeline is an http scrape of a web based Lucene application via
http calls. The scrape outputs a CSV file that we then upload to HDFS and
use it as input to run a spark ML job.

*Question: *Is there a way for our spark application to read from a lucene
index stored in HDFS?  Specifically, I see here
solr-core has an hdfs directory type that seems to be compatible with our
lucene indexreader. Is this compatible? Are we able to store our index in
HDFS and read from a spark job?
