hbase-regionserver. --------------1 解决----
root@cslave2:/]#vi /etc/hbase/conf/hbase-env.sh
注销以下内容：
# Configure PermSize. Only needed in JDK7. You can safely remove it for JDK8+
export HBASE_MASTER_OPTS="$HBASE_MASTER_OPTS -XX:PermSize=128m -XX:MaxPermSize=128m -XX:ReservedCodeCacheSize=256m"
export HBASE_REGIONSERVER_OPTS="$HBASE_REGIONSERVER_OPTS -XX:PermSize=128m -XX:MaxPermSize=128m -XX:ReservedCodeCacheSize=256m" ---------再次启动---------

root@cslave2:/]#vi /etc/hbase/conf/hbase-env.sh
因为hbase/conf目录下的配置不正确导致的，
为hbase/conf/hbase-env.sh添加export HBASE_MANAGES_ZK=false即可。
# Tell HBase whether it should manage it's own instance of Zookeeper or not.
# export HBASE_MANAGES_ZK=true
追加：
export HBASE_MANAGES_ZK=false ---------第六次启动---------

发现有些错误信息是昨晚的，所以打算删掉日志，再重新启动HRegionServer服务，再查看日志
没有具体错误信息 -----------------------------问题解决，批量启动服务------操作回顾------
总结：修改了vi /etc/hbase/conf/hbase-env.sh /etc/hbase/conf/hbase-site.xml
root@cslave2:/]#mkdir -p /var/hadoop
root@cslave2:/var]#chown -R hbase:hbase /var/hadoop/

root@cslave1:/]#/usr/sbin/ntpdate 192.168.1.120 ------------再次启动cSlave1上的HRegionServer服务----------
root@cSlave1:/etc/hbase/conf]#sudo service hbase-regionserver start
此时，启动错误，但jps成功
主节点端口60010上，新增cSlave1节点 问题总结111：新节点要进行以下操作：
mkdir -p /var/hadoop
chown -R hbase:hbase /var/hadoop/
yum install -y ntpdate
/usr/sbin/ntpdate 192.168.1.120 sudo service hbase-regionserver start ---------------------------------其余节点运行 问题总结111命令----
sudo service hbase-master restart #cmaster --------cMaster 问题---------------
