the local-dirs folder has next folders after failed start effort - filecache, nmprivate, 3 usercache_del_timestamp. based on location of error(resourcelocalizationservice.java, line 233), 3 possible actions raise error - a) cleaning old files - works, reflected in log output b) creating new files - after failed start attempt, see 3 kinds of files in local-dirs - 3 usercache_del_*, filecache, nmprivate files. c) making log paths - have checked log folders have permission 775 yarn:hadoop.

what perchance going wrong? i'm using cloudera manager cluster.

you should allow nodemanager dir have executive power, chmod 700 ..(nodemanager dir)

java hadoop yarn cloudera-manager cloudera-cdh
