title: Error changing solr schema
body: <p>I'm very very new to solr. I launched a Bitnami VMI on Amazon AWS just this morning.</p>
  
  <p>After some googling I found how to use putty to ssh to the box, use filezilla to sftp files etc. I wanted to change the fields in the schema, so i downloaded the schema.xml file from collecction1, modified it and re-uploaded it.</p>
  
  <p>After which, I ran a reload command, but am now getting an error.</p>
  
  <p>collection1: org.apache.lucene.store.LockObtainFailedException:org.apache.lucene.store.LockObtainFailedException: Lock obtain timed out: NativeFSLock@/opt/bitnami/apache-solr/solr/collection1/data/index/write.lock: java.io.FileNotFoundException: /opt/bitnami/apache-solr/solr/collection1/data/index/write.lock (Permission denied)</p>
  
  <p>I can see that the write.lock file is present on the filesystem, so I'm not sure why im getting this error.</p>
  
  <p>Any help would be appreciated.</p>
  
  <p>Thanks
  Al</p>
