Hello,
We are using TikaEntityProcessor to extract the content out of PDF and make the
content searchable.
When jetty is run on windows based machine, we are able to successfully load
documents using full import DIH(tika entity). Here PDF's is maintained in
windows file system.
But when jetty solr is run on linux machine, and try to run DIH, we are getting
below exception: (Here PDF's are maintained in linux filesystem)
Full Import failed:java.lang.RuntimeException: java.lang.RuntimeException:
