这个输出信息是启动 HBase 的过程中出现的，其中有多个 SLF4J 绑定的警告信息，这是由于 HBase 和 Hadoop 都依赖了 SLF4J，并且使用了不同版本的 jar 包导致的。这个警告信息可以忽略，不会影响 HBase 的正常使用。如果你想要解决这个警告信息，可以尝试将 Hadoop 和 HBase 使用的 SLF4J 版本统一。另外，最后一行的输出信息表明 HBase 启动成功，可以正常使用。

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。
