I have downloaded the .tar.gz file and tried bringing up logstash through the logstash script. I am unable to bring up any of the 7.10.2 versions of logstash with the below error. I see posts about the permissions of the directory where the logs are written. They seem to have the right permissions. But still my issue isnt solved. Any help would be appreciated. ```auto 2021-06-07 18:15:17,956 main ERROR Unable to locate plugin type for PipelineRoutingFilter 2021-06-07 18:15:17,957 main ERROR Unable to locate plugin type for PipelineRoutingFilter 2021-06-07 18:15:17,958 main ERROR Unable to locate plugin type for PipelineRouting 2021-06-07 18:15:18,088 main ERROR Unable to locate plugin for PipelineRoutingFilter 2021-06-07 18:15:18,091 main ERROR Could not create plugin of type class org.apache.logging.log4j.core.appender.RollingFileAppender for element RollingFile: java.lang.NullPointerException java.lang.NullPointerException 2021-06-07 18:15:18,092 main ERROR Unable to invoke factory method in class org.apache.logging.log4j.core.appender.RollingFileAppender for element RollingFile: java.lang.IllegalStateException: No factory method found for class org.apache.logging.log4j.core.appender.RollingFileAppender java.lang.IllegalStateException: No factory method found for class org.apache.logging.log4j.core.appender.RollingFileAppender at org.apache.logging.log4j.core.config.plugins.util.PluginBuilder.findFactoryMethod(PluginBuilder.java:234) at org.apache.logging.log4j.core.config.plugins.util.PluginBuilder.build(PluginBuilder.java:134) at org.apache.logging.log4j.core.config.AbstractConfiguration.createPluginObject(AbstractConfiguration.java:1002) at org.apache.logging.log4j.core.config.AbstractConfiguration.createConfiguration(AbstractConfiguration.java:942) at org.apache.logging.log4j.core.config.AbstractConfiguration.createConfiguration(AbstractConfiguration.java:934) at org.apache.logging.log4j.core.config.AbstractConfiguration.doConfigure(AbstractConfiguration.java:552) at org.apache.logging.log4j.core.config.AbstractConfiguration.initialize(AbstractConfiguration.java:241) at org.logstash.log.LogstashConfigurationFactory.getConfiguration(LogstashConfigurationFactory.java:64) at org.logstash.log.LogstashConfigurationFactory.getConfiguration(LogstashConfigurationFactory.java:36) at org.apache.logging.log4j.core.config.ConfigurationFactory.getConfiguration(ConfigurationFactory.java:302) at org.apache.logging.log4j.core.config.ConfigurationFactory$Factory.getConfiguration(ConfigurationFactory.java:459) at org.apache.logging.log4j.core.config.ConfigurationFactory.getConfiguration(ConfigurationFactory.java:323) at org.apache.logging.log4j.core.LoggerContext.reconfigure(LoggerContext.java:687) at org.apache.logging.log4j.core.LoggerContext.setConfigLocation(LoggerContext.java:676) at org.logstash.log.LoggerExt.reconfigure(LoggerExt.java:180) 2021-06-07 18:15:18,095 main ERROR Unable to locate plugin for PipelineRoutingFilter 2021-06-07 18:15:18,095 main ERROR Could not create plugin of type class org.apache.logging.log4j.core.appender.RollingFileAppender for element RollingFile: java.lang.NullPointerException java.lang.NullPointerException at org.apache.logging.log4j.core.config.plugins.visitors.PluginElementVisitor.findNamedNode(PluginElementVisitor.java:104) at org.apache.logging.log4j.core.config.plugins.visitors.PluginElementVisitor.visit(PluginElementVisitor.java:88) at org.apache.logging.log4j.core.config.plugins.util.PluginBuilder.injectFields(PluginBuilder.java:185) at org.apache.logging.log4j.core.config.plugins.util.PluginBuilder.build(PluginBuilder.java:121) at org.apache.logging.log4j.core.config.AbstractConfiguration.createPluginObject(AbstractConfiguration.java:1002) at org.apache.logging.log4j.core.config.AbstractConfiguration.createConfiguration(AbstractConfiguration.java:942) at org.apache.logging.log4j.core.config.AbstractConfiguration.createConfiguration(AbstractConfiguration.java:934) at org.apache.logging.log4j.core.config.AbstractConfiguration.doConfigure(AbstractConfiguration.java:552) at org.apache.logging.log4j.core.config.AbstractConfiguration.initialize(AbstractConfiguration.java:241) at org.logstash.log.LogstashConfigurationFactory.getConfiguration(LogstashConfigurationFactory.java:64) at org.logstash.log.LogstashConfigurationFactory.getConfiguration(LogstashConfigurationFactory.java:36) at org.apache.logging.log4j.core.config.ConfigurationFactory.getConfiguration(ConfigurationFactory.java:302) at org.apache.logging.log4j.core.config.ConfigurationFactory$Factory.getConfiguration(ConfigurationFactory.java:459) at org.apache.logging.log4j.core.config.ConfigurationFactory.getConfiguration(ConfigurationFactory.java:323) at org.apache.logging.log4j.core.LoggerContext.reconfigure(LoggerContext.java:687) at org.apache.logging.log4j.core.LoggerContext.setConfigLocation(LoggerContext.java:676) ``` ---

You would need to provide more detail. What are the non-comment lines in logstash.yml? What command line are you using to start logstash? ---
