Re: Cannot start App Timeline Server...Need help please :'(

@Ashikin

Based on the error message it looks like the component failed to start because namenodes are in safemode.


Please check if you can remove namenodes from safe mode as following and then try again.

Get the SafeMode state:

# su - hdfs
# hdfs dfsadmin -safemode get

Leave SafeMode:

# su - hdfs
# hdfs dfsadmin -safemode leave 


It is also better to look at the NameNode log to findout why it is in SafeMode. Is there any repetitive erorr/warning message inside the NameNode logs (if yes then please share the complete log)

Hi Jay, I did the leave safe mode command but it still in safemode. Where can I access NameNode logs? Is it in /var/log/hadoop/hdfs?

Re: Cannot start App Timeline Server...Need help please :'(

@Ashikin

Yes, the NameNode logs can be found inside the file with some name like (where xxxxx will be usually the hostname)

/var/log/hadoop/hdfs/hadoop-hdfs-namenode-xxxxxxx.log

.

It is better to take a look at both Active and StandBy NameNode logs.

Also you should try restarting the AppTimeline Server using command line once to see if it goes well, as described in :

https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.2/bk_reference/content/starting_hdp_services....

Execute this command on the timeline server:

su -l yarn -c "/usr/hdp/current/hadoop-yarn-timelineserver/sbin/yarn-daemon.sh start timelineserver"

.

It will be also a good idea to try starting the Application Timeline Server using command line once as described in the link: https://docs.hortonworks.com/HDPDocuments/HDP2/HDP-2.6.2/bk_reference/content/starting_hdp_services....
