i am getting an error in PullContentStream Processor in nifi i.e. can not connect to localhost:2181/solr cluster not found/cluster not ready. HELP ME
to resolve this nifi error i removed write.lock file from location /opt/lucidworks-hdpsearch/solr/docs .
Please take a look at this attachment which is showing error in processor PutSolrContentStream.
this only shows that it is not able to connect to localhost:2181/solr. Log file always tells you the extra information.
You can try restarting Solr from Ambari and then start Nifi workflow again
