We are trying to bring up the HDP cluster via ambari. For some reason zookeeper doesn't come up. It is throwing the below log in /var/log/zookeeper/
"Error occurred during initialization of VM
Too small initial heap"
Can you help on Probable debug steps.
Check SERVER_JVMFLAGS in /etc/zookeeper/conf/zookeeper-env.sh.
It would be of the type: export SERVER_JVMFLAGS=-Xmx1024m
Try increasing the same via Ambari - zookeeper-env and restart zookeeper
