Solr appears write Lock, solrexception: could not get leader props in the log

Take over other people's projects , on-line Solr One machine in the cluster is down , Restart reported such an error , I searched around and couldn't find a solution , Skull pain . Tossed all afternoon

The screenshot of the error reporting problem is as follows :


Solution :
1. Delete all write.lock file .
2. Use root Account plus -force Parameter startup . But the official does not recommend root Account activation , But at least it solves the problem . The order is as follows :

`/work/.../solr/bin/solr start -force`

Yes solr Not familiar with , It's solved by tossing and turning … Just record it like this
