ok , we meed to find the path's for the changing

mike_bronson7 · ‎12-02-2019

we got the following , because missing PATH $ hdfs dfs -chown airflow:hdfs -chown: Not enough arguments: expected 2 but got 1 Usage: hadoop fs [generic options]

mike_bronson7 · ‎12-02-2019

Dear Shelton do you mean : grep airflow /etc/passwd airflow:x:1016:1016::/home/airflow:/sbin/nologin # id 1016 uid=1016(airflow) gid=1016(airflow) groups=1016(airflow),1005(hdfs) so we need to perform : $ hdfs dfs -chown airflow:1016 ?

how to found the airflow_group ?

we are runs spark application on hadoop cluster ( HDP version - 2.6.5 from hortonworks ) from the logs we can see the following Diagnostics User: airflow Application Type: SPARK User class threw exception: org.apache.hadoop.security.AccessControlException: Permission denied. user=airflow is not the owner of inode=alapati not clearly what we need to search in `HDFS` in order to find why we get Permission denied

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 · ‎11-26-2019

so lets summary to avoid mistake rhel 7.7 can support HDP 2.6.4 and up ( latet HDP version ) rhel 7.7 can support 2.6.2.2 , 2.7.3 , 2.7.4 ambari version is it correct until now? second when current rhel version is 7.2 and we want to add rhel 7.7 OS version then its fully recommended to upgrade 7.2 to 7.7 is it correct ?

mike_bronson7 · ‎11-26-2019

hi Shelton you mention to upgrade to version 7.7 but https://supportmatrix.hortonworks.com/ , when you click on 7.7 , we not see any selected HDP or ambari so I gues you means to upgrade to 7.6 version ( because 7.7 not approved for any HDP )

thank you so much , by the way I posted a new question about mixing RHEL 7.2 with 7.5 , I will very happy if you can answer on that question also
