> 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.
