[NIFI-5269] NiFi doesn't start if bootstrap.conf contains a tmp dir which doesn't exist

• Type: Bug

Description

If a "java.io.tmpdir" argument is added to bootstrap.conf, and that directory does not exist, the PutHiveStreaming processor cannot be instantiated due to a SnappyError FAILED_TO_LOAD_NATIVE_LIBRARY.  A possible solution to this would be to add a check in RunNiFi.java[1]

 

final String tmpDirProperty = "-Djava.io.tmpdir=";
final List<String> javaAdditionalArgs = new ArrayList<>();

for (final Map.Entry<String, String> entry : props.entrySet()) {
     final String key = entry.getKey();
     final String value = entry.getValue();

     if (key.startsWith("java.arg")) {

          javaAdditionalArgs.add(value);

          if(value.startsWith(tmpDirProperty) 
               && value.length() > tmpDirProperty.length()){

               String tmpDir = value.subString(tmpDirProperty.length());
               Files.createDirectories(Paths.get(tmpDir));
          }
     }
}
