这个错误提示表明有多个SLF4J绑定，导致启动HBase时出现了异常。这个问题是由于Hadoop和HBase等软件包都有自己的SLF4J依赖，导致多个版本的SLF4J库同时存在，从而引发冲突。

解决方法是在HBase的启动脚本中添加以下命令，清除Hadoop的SLF4J依赖：

export HBASE_OPTS="-Dhadoop.metrics.log.level=WARN -Dorg.slf4j.simpleLogger.log.org.apache.hadoop=WARN -Dorg.apache.commons.logging.Log=org.apache.commons.logging.impl.NoOpLog"

另外，错误提示中还显示了无法解析zk1、zk2、zk3这几个主机名。这是因为HBase在启动时需要连接ZooKeeper，但是无法解析这几个主机名。需要确认ZooKeeper的主机名配置是否正确，并且确保当前主机可以正常访问这几个主机。可以尝试使用ping命令测试这几个主机是否可达。

这个错误信息显示了多个 SLF4J 绑定的问题，以及一个无法创建目录和找不到日志文件的问题。

针对这些问题，可以尝试以下解决方法：

1. 多个 SLF4J 绑定的问题可以忽略，因为实际绑定的是 Log4jLoggerFactory。

2. 创建目录和日志文件的问题，可能是因为没有写入权限导致的。可以尝试使用 root 用户或者具有写入权限的用户来启动 HBase。

另外，你可以进入 HBase 的 bin 目录下，手动创建 logs 目录，以及在 logs 目录下创建 hbase-atguigu-master-node11.out 文件，然后再次尝试启动 HBase。例如：

cd /usr/local/hbase/bin
sudo mkdir ../logs
sudo touch ../logs/hbase-atguigu-master-node11.out
sudo chmod -R 777 ../logs
./start-hbase.sh

如果问题仍然存在，请提供更多信息，我会尽力帮助你解决。

这是一个启动HBase的Shell脚本，在启动的过程中出现了SLF4J绑定的问题。具体的错误信息是Class path contains multiple SLF4J bindings，意思是类路径中包含了多个SLF4J绑定。在这个错误信息中，SLF4J发现了两个绑定，一个在/opt/module/hadoop-3.1.3/share/hadoop/common/lib/slf4j-log4j12-1.7.25.jar中，另一个在/usr/local/hbase/lib/client-facing-thirdparty/slf4j-log4j12-1.7.30.jar中。SLF4J提供了一个链接http://www.slf4j.org/codes.html#multiple_bindings来解释这个问题。最后，该错误信息指出实际的绑定类型是org.slf4j.impl.Log4jLoggerFactory。
