hadoop - Running Map Reduce Job shows error - Mkdirs failed to create /var/folders/ -


when running map reduce job in mac terminal as:

pawandeepsingh1$ hadoop jar maximumtemperature.jar exception in thread "main" java.io.ioexception: mkdirs failed create /var/folders/v1/lyx_f0rj615cy8s54_bk053h0000gp/t/hadoop-unjar3698429834837790177/meta-inf/license     @ org.apache.hadoop.util.runjar.ensuredirectory(runjar.java:128)     @ org.apache.hadoop.util.runjar.unjar(runjar.java:104)     @ org.apache.hadoop.util.runjar.unjar(runjar.java:81)     @ org.apache.hadoop.util.runjar.run(runjar.java:209)     @ org.apache.hadoop.util.runjar.main(runjar.java:136)

i have seen similar question says don't have permissions run job. can give me step wise solution.

thank in advance

you don't have permission on hdfs filesystem create dirs job. submitting cluster or running local testing environment. can su user has perms /var folders on hdfs? if aren't admin on cluster need have admin either add group ( hdfs, hadoop) have permissions on hdfs or give permissions run jobs privileged user either sudo or ability su.
