In a Kerberos environment,
a Kerberos ticket (TGT) is necessary to run the qkbpush.sh script.
This script copies the QKB to each data node in the cluster and uploads
metadata about it to HDFS.
To create the ticket:
-
Log on as root.
-
Change to the hdfs user.
-
Run kinit.
-
Exit back to root.
-
Run the qkbpush.sh script.
The following are examples
of commands that you might use to obtain the ticket.
su - root
su - hdfs
kinit -kt hdfs.keytab hdfs
exit
Note: You must supply the root
password for the first command.
