The QKB can be removed
from the Hadoop cluster by executing the qkb_push.sh executable file
with the -r flag. You
must have root access to execute qkb_push.sh.
Note: If you are removing the entire
in-database deployment, you must remove the QKB first.
Execute the file as
follows:
cd EPInstallDir/SASEPHome/bin
./qkb_push.sh -r
The -r flag
removes the QKB index file from HDFS and the QKB from all nodes by
default. qkb_push.sh does not list the names of the nodes from which
the QKB is removed in its normal processing. To create a list, specify
the -v flag. Specify the -h or -f flag
in conjunction with the -r flag,
as appropriate, to remove the QKB from a specific node or group of
nodes.
Note: The QKB index file is not
removed from HDFS when the -h or -f flag
is specified with -r.
