# 排查步骤
# 1. 查看日志
$ tail -100 /var/log/hbase/hbase-hbase-master-fgedu-node1.log

# 2. 检查ZooKeeper连接
$ zkCli.sh -server fgedu-node1:2181
ls /hbase

# 3. 检查HDFS目录
$ hdfs dfs -ls /hbase

# 解决方案
# 1. 检查ZooKeeper状态
$ zkServer.sh status

# 2. 检查HDFS状态
$ hdfs dfsadmin -report

# 3. 清理并重启
$ rm -rf /tmp/hbase/*
$ hdfs dfs -rm -r /hbase
$ hdfs dfs -mkdir -p /hbase
$ hdfs dfs -chown hbase:hadoop /hbase
$ /bigdata/app/hbase/bin/start-hbase.sh

# 排查步骤
# 1. 检查网络
$ ping fgedu-node1

# 2. 检查端口
$ telnet fgedu-node1 16000

# 3. 检查防火墙
$ firewall-cmd –list-ports

# 解决方案
# 1. 开放端口
$ firewall-cmd –add-port=16000/tcp –permanent
$ firewall-cmd –add-port=16010/tcp –permanent
$ firewall-cmd –add-port=16020/tcp –permanent
$ firewall-cmd –add-port=16030/tcp –permanent
$ firewall-cmd –reload

# 2. 检查hosts配置
$ cat /etc/hosts

# 3. 重启RegionServer
$ /bigdata/app/hbase/bin/hbase-daemon.sh stop regionserver
$ /bigdata/app/hbase/bin/hbase-daemon.sh start regionserver
