Twitter Analysis via FLUME - Why can't I view the log?

avatar

Hi

I'm trying to view the twitter agent log, however I can't as per below:

[root@sandbox ~]# hdfs dfs -chmod 777 /user/flume/tweets

chmod: changing permissions of '/user/flume/tweets': Permission denied. user=root is not the owner of inode=tweets

[root@sandbox ~]# /var/log/flume/flume-TwitterAgent.log

-bash: /var/log/flume/flume-TwitterAgent.log: Text file busy

I'm trying to use flume to retrieve tweets based on some given keywords, but not having any luck, please can someone advise?

Thanks

Raf

you can likely try using the hdfs user by su'ing to it first: su - hdfs

Then try the chmod again as the hdfs user instead of the root user.

Could I delete the TwitterAgent.log file and try to re populate it? 😕

[root@sandbox ~]# ls /var/log/flume/

TwitterAgent.outflume-TwitterAgent.log
