I would like to upgrade my sandbox to 2.3.4 but I cannot do this because My Namenode is not HA.
Is upgrading to Ambari 2.2 and then doing express upgrade my only option or is there a manual way as well.
I did hdp-select all 2.3.4xxx and most things work but the hdp/apps file in HDFS are old and some other things do not work as well.
( I know this is not how you normally would do it but I am looking for the quickest way to have a new cluster )
Rolling upgrade is not allowed without Namenode HA which the sandbox doesn't have.
I suppose I should stop using the sandbox for real work and do quickstart as well.
Definitely an option but I wanted a quick and dirty option to be up as fast as possible. Ah well I should definitely use quickstart.
That seems to be the common refrain :-). I will upgrade ambari to 2.2 and see if I can use express upgrade for this. If it doesn't work I will close the question.
Ok uopgrading to Ambari 2.2 and use express upgrade seems to work even if its a challenge to start all services with the memory restrictions.
