I'm configuring Solr to store index data file in HDFS.
bin/solr start -e cloud -c -Dsolr.directoryFactory=HdfsDirectoryFactory -Dsolr.lock.type=hdfs -Dsolr.hdfs.home=hdfs://localhost:50070/solr
when I tried to open solr's url and I got error as "SolrCore Initialization Failures", Problem creating directory.
The port used seems wrong
hdfs://localhost:50070/solr
Try hdfs://localhost:8020/solr
you can see the hdfs port in your core-site.xml.
