I am running a System87 Oryx Pro laptop with Ubuntu 18.04 I had only Oracle Java 11 installed for Hadoop, so I also installed OpenJDK8 with: $ sudo apt-get install openjdk-8-jre and switched to it with $ sudo update-java-alternatives --set path/shown/with/"update-java-alternatives --list"
$ java-version openjdk version "1.8.0_191" OpenJDK Runtime Environment (build 1.8.0_191-8u191-b12-2ubuntu0.18.04.1-b12) OpenJDK 64-Bit Server VM (build 25.191-b12, mixed mode) I installed Cassandra according to the directions on http://cassandra.apache.org/doc/latest/getting_started/installing.html, using the "Install from debian packages" instructions. Now when I run $ sudo service cassandra start There are no errors, no feedback to stdout. I assume that's expected behavior? However, this fails: $ nodetest status error: null -- StackTrace -- java.lang.NullPointerException at org.apache.cassandra.config.DatabaseDescriptor.getDiskFailurePolicy(DatabaseDescriptor.java:1892) at org.apache.cassandra.utils.JVMStabilityInspector.inspectThrowable(JVMStabilityInspector.java:82) at org.apache.cassandra.io.util.FileUtils.<clinit>(FileUtils.java:79) at org.apache.cassandra.utils.FBUtilities.getToolsOutputDirectory(FBUtilities.java:860) at org.apache.cassandra.tools.NodeTool.printHistory(NodeTool.java:200) at org.apache.cassandra.tools.NodeTool.main(NodeTool.java:168) Can anyone help me fix this?
