Issue: When running hive shell in a docker you will be getting a message "mbind: Operation not permitted" printed on the console but the operations will pass. . Root Cause: mbind syscall is used for NUMA (non-uniform memory access) operations which is blocked by docker by default. But in hive opts there is an option which specifies '+UseNUMA'. . Resolution: Go to Ambari -> Hive -> Configs -> Advanced 1) Remove '-XX:+UseNUMA' from 'hive.tez.java.opts'. 2) Remove '-XX:+UseNUMA' from hive-env template. Hope this helps 🙂 ... View more

@Michael Bronson, Replace {host-name} with the host name where App timeline server is installed. From your output in the question looks like App time line server is installed on "master01.sys67.com". So you can try this url curl -u $USER:$PASSWORD -X GET -H "X-Requested-By: ambari" http://localhost:8080/api/v1/clusters/HDP/hosts/master01.sys67.com/host_components/APP_TIMELINE_SERVER?fields=HostRoles/state Thanks, Aditya ...

All, Just adding for knowledge gain , if my source is kerberos enabled while target is not , then the command to be executed will be hadoop distcp -D ipc.client.fallback-to-simple-auth-allowed=true webhdfs://source-ip webhdfs://target-ip hadoop distcp -D ipc.client.fallback-to-simple-auth-allowed=true : this command overrides values present in the hive-site.xml. thanks, Rishit Shah ...
