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。
