I know the hostname of the machine, i have already looked in the /var/lib/ambari-agent/data both on the machine added to the cluster and on the ambari server host , these files are not present anywere, and I am absolutely sure nobody deleted them , normally when the log is saved the whole path is showed in UI "Operations" history link...the reason I posted this question is because I cannot find any details about why the installation has timed out ... ...

How do I find timeout reason ?

Hello, I am using REST API to automatically install only KERBEROS_CLIENT and HDFS_CLIENT on a machine. The operations has timedout during the Finalize Operation phase of the HDFS_CLIENT. The only output I can see is : stderr: errors-2277.txtstdout: output-2277.txt Is there any way to see these messages ? The status of the task was FAILED but without any reason. The host I am adding has an agent installed and manually configured and the communication works fine since the packages were installed.... Any suggestion is appreciated :). Thanks, Corina ...

the kinit is not an issue, i know how to manage that, i am actually creating a new keytab for that user...and then I am able to access hdfs if I add read permissions on hdfs-site... hdfs-site has no reading permissions by default if I only install the hdfs_client . I have tested adding new clients (yarn_client for example) and then the reading permissions are added to hdfs-site, I am not sure why ... ... View more

I have already tested it , it seems that it does not change the permissions unless the file is deleted, if so when it recreates it (refresh config issued from ambari) it recreates it without reading permissions, i was hoping for a solution that would cover this case also ... View more

Hello, I have used ambari rest api to install only kerberos and hdfs clients on a machine from my cluster. I am unable to access the hdfs (hadoop fs -ls / command) with a user not belonging to hadoop group because there are no reading permission for /etc/hadoop/2.4.2.0-258/0/hdfs-site.xml. My question is : if I manually give permissions to this file will ambari modify them if on cluster level there will be an update on the hdfs-site.xml ? Are you aware of this issue ? Is there known workaround? I want to limit the packages installed on this node(i do not wish to install all the clients as done by ambari gui). Thank you, Corina ... View more
