Hi Team,

is anyone aware of issues during installation , that why do we get so many broken symlink issues during installation , this issue i faced in HDP 2.3.4 and ambari-2.2.2.0

Please see below

https://community.hortonworks.com/questions/33492/hdp-234-failed-parent-directory-usrhdpcurrenthadoo...

i was installing 3 Node HDP 2.4.0.0 cluster, wherein at step "Install,Start and Test"

on 1 node installation went fine but on other 2 nodes there were random symlink issues

i had to fix broken symlink issues manually most of the times and final after spending so much time i was able to successfully installed HDP 2.4.0.0

issues like as below and shown in image

2016-08-18 21:20:17,474 - Directory['/etc/hive'] {'mode': 0755}

2016-08-18 21:20:17,474 - Directory['/usr/hdp/current/hive-client/conf'] {'owner': 'hive', 'group': 'hadoop', 'recursive': True}

2016-08-18 21:20:17,474 - Creating directory Directory['/usr/hdp/current/hive-client/conf'] since it doesn't exist

I had proper prerequisites available before starting installation as given in http://docs.hortonworks.com/HDPDocuments/Ambari-2.2.2.0/bk_Installing_HDP_AMB/content/_hdp_24_reposi...

also randomly doing retries it works 😞

Please advise if you think i am doing something wrong or any good best practices for installation and debugging

Thanks,

refer to manual installation doc for hdp-select to fix your symlink issues https://docs.hortonworks.com/HDPDocuments/Ambari-2.1.2.0/bk_upgrading_Ambari/content/_Run_HDP_Select... when you have a specific error open a question, generally you shouldn't get these errors.
