> ContainerLogsUtils#getContainerLogFile fails to read files from full disks.
> {{getContainerLogFile}} depends on {{LocalDirsHandlerService#getLogPathToRead}} to get
the log file, but {{LocalDirsHandlerService#getLogPathToRead}} calls {{logDirsAllocator.getLocalPathToRead}}
and {{logDirsAllocator}} uses configuration {{YarnConfiguration.NM_LOG_DIRS}}, which will
be updated to not include full disks in {{LocalDirsHandlerService#checkDirs}}:
> {code}
>     Configuration conf = getConfig();
>     List<String> localDirs = getLocalDirs();
>     conf.setStrings(YarnConfiguration.NM_LOCAL_DIRS,
>                     localDirs.toArray(new String[localDirs.size()]));
>     List<String> logDirs = getLogDirs();
>     conf.setStrings(YarnConfiguration.NM_LOG_DIRS,
>                       logDirs.toArray(new String[logDirs.size()]));
> {code}
> ContainerLogsUtils#getContainerLogFile is used by NMWebServices#getLogs and ContainerLogsPage.ContainersLogsBlock#render
to read the log.
