I now try to set this at end of my bootstrap.conf file: java.arg.snappy=-Dorg.xerial.snappy.tempdir=/usr/hdf/current/nifi/tmp
But this only throws another ERROR to the log that causes nifi to fail: 2022-12-13 15:09:49,284 ERROR [NiFi logging handler] org.apache.nifi.StdErr java.lang.reflect.InaccessibleObjectException: Unable to make protected final java.lang.Class java.lang.ClassLoader.defineC lass(java.lang.String,byte[],int,int,java.security.ProtectionDomain) throws java.lang.ClassFormatError accessible: module java.base does not "opens java.lang" to unnamed module @2326180c 2022-12-13 15:09:49,285 ERROR [NiFi logging handler] org.apache.nifi.StdErr at java.base/java.lang.reflect.AccessibleObject.checkCanSetAccessible(AccessibleObject.java:354) 2022-12-13 15:09:49,285 ERROR [NiFi logging handler] org.apache.nifi.StdErr at java.base/java.lang.reflect.AccessibleObject.checkCanSetAccessible(AccessibleObject.java:297) 2022-12-13 15:09:49,286 ERROR [NiFi logging handler] org.apache.nifi.StdErr at java.base/java.lang.reflect.Method.checkCanSetAccessible(Method.java:199) 2022-12-13 15:09:49,286 ERROR [NiFi logging handler] org.apache.nifi.StdErr at java.base/java.lang.reflect.Method.setAccessible(Method.java:193) 2022-12-13 15:09:49,286 ERROR [NiFi logging handler] org.apache.nifi.StdErr at org.xerial.snappy.SnappyLoader.injectSnappyNativeLoader(SnappyLoader.java:275) 2022-12-13 15:09:49,286 ERROR [NiFi logging handler] org.apache.nifi.StdErr at org.xerial.snappy.SnappyLoader.load(SnappyLoader.java:227) 2022-12-13 15:09:49,286 ERROR [NiFi logging handler] org.apache.nifi.StdErr at org.xerial.snappy.Snappy.<clinit>(Snappy.java:48) 2022-12-13 15:09:49,286 ERROR [NiFi logging handler] org.apache.nifi.StdErr at org.apache.nifi.processors.hive.PutHiveStreaming.<clinit>(PutHiveStreaming.java:158) 2022-12-13 15:09:49,286 ERROR [NiFi logging handler] org.apache.nifi.StdErr at java.base/java.lang.Class.forName0(Native Method) 2022-12-13 15:09:49,286 ERROR [NiFi logging handler] org.apache.nifi.StdErr at java.base/java.lang.Class.forName(Class.java:467) 2022-12-13 15:09:49,286 ERROR [NiFi logging handler] org.apache.nifi.StdErr at org.apache.nifi.nar.StandardExtensionDiscoveringManager.getClass(StandardExtensionDiscoveringManager.java:328) 2022-12-13 15:09:49,286 ERROR [NiFi logging handler] org.apache.nifi.StdErr at org.apache.nifi.documentation.DocGenerator.documentConfigurableComponent(DocGenerator.java:100) 2022-12-13 15:09:49,286 ERROR [NiFi logging handler] org.apache.nifi.StdErr at org.apache.nifi.documentation.DocGenerator.generate(DocGenerator.java:65) 2022-12-13 15:09:49,286 ERROR [NiFi logging handler] org.apache.nifi.StdErr at org.apache.nifi.web.server.JettyServer.start(JettyServer.java:1126) 2022-12-13 15:09:49,286 ERROR [NiFi logging handler] org.apache.nifi.StdErr at org.apache.nifi.NiFi.<init>(NiFi.java:159) 2022-12-13 15:09:49,286 ERROR [NiFi logging handler] org.apache.nifi.StdErr at org.apache.nifi.NiFi.<init>(NiFi.java:71) 2022-12-13 15:09:49,286 ERROR [NiFi logging handler] org.apache.nifi.StdErr at org.apache.nifi.NiFi.main(NiFi.java:303) Some research suggests this may be fixable by setting this as follows, presumably to the java startup: --illegal-access=permit (see cglib - java.lang.ExceptionInInitializerError with Java-16 | j.l.ClassFormatError accessible: module java.base does not "opens java.lang" to unnamed module - Stack Overflow <https://stackoverflow.com/questions/66974846/java-lang-exceptionininitializererror-with-java-16-j-l-classformaterror-access> ) Would I set this in bootstrap.conf?
