@mike_bronson7 You can change the ownership of the HDFS directory to airflow:hadoop please do run the -chown command on / ??? It should something like /users/airflow/xxx Please let me know

Dear Shelton this is very very strange that some application / other delete the files ( there are 4 files while 2 of them represented the md5 chksum ) what we are very worry from this case , is that we actuality not know the real reason why files deleted and we cant reverse and see whats happens

ok so after second thinking I think its better to use the latest version that supported - 7.6 instead of 7.5 rhel 7.6 can support HDP 2.6.4 and up ( latest HDP version ) rhel 7.6 can support 2.6.2.2 , 2.7.3 , 2.7.4 ambari version and when current rhel version is 7.2 and we want to add rhel 7.6 OS version then its fully recommended to upgrade 7.2 to 7.6

@mike_bronson7 The latest command you posted again has typo. "R" is missing at the end in below command - >>curl -u admin:admin -H "X-Requested-By: ambari" -X DELETE "http://node02:8080/api/v1/clusters/HDP/hosts/node01/host_components/SPARK2_THRIFTSERVE" Pls try and pass new error if any.

@mike_bronson7 you just need to backup /hadoop/hdfs/namenode/current from active namenode Also if you backup one week earlier the activity and lets say your first cluster is going serve more request to clients then you will loose that data which was written after backup. So best is to do savenamespace and backup when you are going to do activity and freeze clients not accessing the cluster.

1. Is the job failed due to above reason? If "NO" - then is it the error occurring displayed in logs for all spark jobs or just for this job?

Shelton · ‎11-03-2019

@mike_bronson7 Yes, it's possible to deploy HDF using Ambari blueprints. If you compared an HDP and HDF blueprint you will notice a difference in the components section only. Deploy HDF 1 using a blueprint Deploy HDF 2 using a blueprint Deploy HDF 3 using a blueprint Above are some links that show the possibility
