JBOSS gibt org.apache.kafka.common.KafkaException: auth.conf kann nicht gelesen werden

Question

Wenn ich Krieg meiner einfachen Kafka-Projekt (das funktioniert wie ein Glas) in Wildfly v 10 bereitstellen, bekomme ich einige Zoo Keeper-Verbindung Ausnahme [ 1] .Diese tritt auf, wenn kafka Zuhörer mit zookeeper zu verbinden beginnt

Answer 1

der Fehler durch den folgenden Code in Kafka verursacht wird

String loginConfigFile = System.getProperty(JAVA_LOGIN_CONFIG_PARAM); 
if (loginConfigFile != null && loginConfigFile.length() > 0) { 
     File configFile = new File(loginConfigFile); 
     if (!configFile.canRead()) { 
      throw new KafkaException("File " + loginConfigFile + "cannot be read."); 
     } 
... 

bei Wildfly 10, die Eigentum von JAVAX_LOGIN_CONFIG PARAM (java.security.auth.login.config) ist auf jar:file:/opt/jboss/wildfly/modules/system/layers/base/org/picketbox/main/picketbox-4.9.4.Final.jar!/auth.conf eingestellt.

Bei Wildfly 9 ist die obige Eigenschaft null. Daher besteht die schnelle Problemumgehung darin, Wildfly 9 nachzuahmen, indem Sie diese Eigenschaft auf null setzen.

Um dies zu tun, ändern Sie Ihre Standalone.conf mit -Djava.security.auth.login.config= Option, dh. leerer Wert Meine Standalone.conf wird so aussehen:

if [ "x$JAVA_OPTS" = "x" ]; then 
    JAVA_OPTS="-Xms2048m -Xmx2048m -XX:MetaspaceSize=96M -XX:MaxMetaspaceSize=256m -Djava.net.preferIPv4Stack=true" 
    JAVA_OPTS="$JAVA_OPTS -Djboss.modules.system.pkgs=$JBOSS_MODULES_SYSTEM_PKGS -Djava.awt.headless=true -Djava.security.auth.login.config=" 
else 
    echo "JAVA_OPTS already set in environment; overriding default settings with values: $JAVA_OPTS"
