Troubleshooting

Problem: Intellij not picking up protoc generated classes.

1. There is a file under intellij – generally where you have installed/downloaded intellij.
2. This file is called  /Applications/idea/idea.app/Contents/bin/idea.properties under MacOS and generally under your home directory if you are on Linux.
3. Edit this file, there is a property called
   

4. idea.max.intellisense.filesize=2500 -- set this value to 5000

5. Restart Intellij, this assumes that your editor/ machine has enough RAM to process this file.
   
   

Problem: For Ubuntu 18.04+ the default openjdk is 11, had the following errors:  java: No SupportedSourceVersion annotation found on org.apache.hadoop.hdds.conf.ConfigFileGenerator, returning RELEASE_6.
java: Supported source version 'RELEASE_6' from annotation processor 'org.apache.hadoop.hdds.conf.ConfigFileGenerator' less than -source '8 as well as java: package sun.misc does not exist; 

Through the intellij project structure settings configured to use java 8 sdk to resolve missing sun.misc.SignalHandler issue.
