    Description

      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)

      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.
