iam using hadoop apache 2.7.1 on centos 7 and my cluster is ha cluster and iam using zookeeper quorum for automatic failover
but i want to automate zookeeper start process and ofcourse in the shell script we have to stop firewall first in order to let other quorum elements able to contact current zookeeper element
iam writing the following script in /etc/rc.d/rc.local
systemctl stop firewalld
ZOOKEEPER='/usr/local/zookeeper-3.4.9/' source /etc/rc.d/init.d/functions
daemon --user root $ZOOKEEPER/bin/zkServer.sh start
but iam facing the problem that when iam issuing the command
systemctl stop firewalld in rc.local
and issuing zkServer status after host boots iam getting the error
ZooKeeper JMX enabled by default Using config: /usr/local/zookeeper-3.4.9/bin/../conf/zoo.cfg Error contacting service. It is probably not running.
but if i execute the same commands with out a script i mean after my host boots as normal process
systemctl status firewalld
there is no problem and zkstatus shows its mode
i have noticed the difference in zookeeper.out log between executing rc.local script and normal commands after the host boots
and the difference is reading server environments in normal commands execute
what could be the effect of stopping firewall at rc.local script to server environment and how to handle it ?
