Removing the QKB from Hadoop

The QKB can be removed from a Hadoop cluster by executing the qkbpush.sh script with the -r flag. The -r flag removes the QKB index file from HDFS and the QKB from all nodes by default. Specify the -h or -f flags in conjunction with the -r flag, as appropriate, to remove the QKB from a subset of the nodes. After running the script, restart the SAS Embedded Process, so that the changes can take effect.
The QKB index file is not removed from HDFS when the -h or -f flag is specified.
