             Summary: NPE when accessing container logs due to null dirsHandler
                 Key: YARN-7396
                 URL: https://issues.apache.org/jira/browse/YARN-7396
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Jonathan Hung


{noformat}java.lang.NullPointerException
	at org.apache.hadoop.yarn.server.nodemanager.webapp.NMWebAppFilter.containerLogPageRedirectPath(NMWebAppFilter.java:96)
	at org.apache.hadoop.yarn.server.nodemanager.webapp.NMWebAppFilter.doFilter(NMWebAppFilter.java:62)
	at com.sun.jersey.spi.container.servlet.ServletContainer.doFilter(ServletContainer.java:829){noformat}
In YARN-6620 the NMContext creation in {{NodeManager#serviceInit}} was moved. It's now created before the dirsHandler is initialized. So when {{nmContext.getLocalDirsHandler}} is called, it's null.
