Description

If the auto-load NARs directory has not read+write access, NiFi won't start:

java.io.IOException: /tmp/nifi-extensions directory does not have read/write privilege
 at org.apache.nifi.util.FileUtils.ensureDirectoryExistAndCanReadAndWrite(FileUtils.java:51)
 at org.apache.nifi.nar.NarAutoLoader.start(NarAutoLoader.java:56)
 at org.apache.nifi.web.server.JettyServer.start(JettyServer.java:1051)
 at org.apache.nifi.NiFi.<init>(NiFi.java:158)
 at org.apache.nifi.NiFi.<init>(NiFi.java:72)
 at org.apache.nifi.NiFi.main(NiFi.java:301)

Read only access is enough to this directory.
