If the /etc/gphd/zookeeper/conf/java.env does not exist then create it.  Add the following entry to set zookeeper max heapsize to 1024MB.  Then restart the zookeeper service.

如果/etc/gphd/zookeeper/conf/java.env文件不存在，这创建它。并且设置zookeeper最大heapsize为1024MB。然后启动zookeeper      

export JVMFLAGS="-Xmx724m -Xms724m"      

调整zookeeper heap大小，目的在于避免oom，同时减少sawp空间交换带来的性能下降。
