hypertable-0.9.6.5.59309c4-linux-x86_64.tar.gz
new Hypertable Version:

(1) download 0.9.7.7 rpm file
ssh to master01 as root user:
[root@master01~] cd /mnt/nfssvr/extras/hypertable/rpm
[root@master01 rpm]# wget http://cdn.hypertable.com/packages/0.9.7.7/hypertable-0.9.7.7-linux-x86_64.rpm
(2) upgrading
(a) stop your hypertable cluster(my Capfile is in /root)
[root@master01 rpm] cd ~
[root@master01 rpm] cap stop
[root@master01 rpm] ps -ef | grep hyper
# if there was any process exist, stop it
[root@master01 rpm] /opt/hypertable/current/bin/stop-servers.sh
(b) modify your Capfile
[root@master01 rpm] cd ~
[root@master01 ~] vi Capfile
:
#set :hypertable_version, "0.9.6.5.59309c4"
set :hypertable_version, "0.9.7.7"
#set :default_pkg, "/mnt/nfssvr/extras/hypertable/rpm/hypertable-0.9.6.5.59309c4-linux-x86_64.tar.gz"
set :default_pkg, "/mnt/nfssvr/extras/hypertable/rpm/hypertable-0.9.7.7-linux-x86_64.rpm"
