这个错误提示说了两个问题：

1. 发现了多个 SLF4J 日志绑定。这通常发生在在一个应用程序中包含多个不同版本的 SLF4J 库时。这可能会导致日志记录错误或日志重复。可以通过删除其中一个或将其排除来解决此问题。

2. 找不到 Hive 库。这很可能是因为您没有正确设置 Hive 的类路径。您需要在 flume 的 classpath 中包含 Hive 相关的库。可以尝试设置 HIVE_HOME 环境变量并将 $HIVE_HOME/lib 添加到 flume 的 classpath 中，或者手动添加 Hive 相关的 jar 包到 flume 的 classpath 中。

要解决这些问题，您可以尝试以下步骤：

1. 检查 flume 和 Hadoop 版本是否兼容。如果不兼容，可能会导致类路径问题和其他错误。建议使用 Hadoop 2.x 版本与 flume 1.x 版本搭配使用。

2. 检查 flume 的 classpath 是否正确设置。确保 flume 的 classpath 包含 Hive 相关的库。

3. 检查 SLF4J 日志绑定问题。如果存在多个 SLF4J 日志绑定，可以删除其中一个或将其排除。

希望这些信息可以帮助您解决问题。

这也是一段日志信息，Flume在启动时输出的。它告诉你Flume正在为HDFS和Hive访问加载相关的库文件。在这个日志中，Flume加载了Hadoop和Hive的库文件，以便它可以访问HDFS和Hive。这些库文件通常位于Hadoop和Hive的安装目录下的lib目录中。Flume的日志信息可以帮助你了解它在启动时做了哪些操作，以及它的配置是否正确。

启动flume是报以下错误Info: Including Hadoop libraries found via (/opt/software/hadoop-2.8.3/bin/hadoop) for HDFS access Info: Including Hive libraries found via (/opt/software/hive-2.3.3) for Hive access + exec /opt/jdk1.8.0_261/bin/java -Xmx20m -cp '/opt/software/flume-1.8.0/conf:/opt/software/flume-1.8.0/lib/*:/opt/software/hadoop-2.8.3/etc/hadoop:/opt/software/hadoop-2.8.3/share/hadoop/common/lib/*:/opt/software/hadoop-2.8.3/share/hadoop/common/*:/opt/software/hadoop-2.8.3/share/hadoop/hdfs:/opt/software/hadoop-2.8.3/share/hadoop/hdfs/lib/*:/opt/software/hadoop-2.8.3/share/hadoop/hdfs/*:/opt/software/hadoop-2.8.3/share/hadoop/yarn/lib/*:/opt/software/hadoop-2.8.3/share/hadoop/yarn/*:/opt/software/hadoop-2.8.3/share/hadoop/mapreduce/lib/*:/opt/software/hadoop-2.8.3/share/hadoop/mapreduce/*:/contrib/capacity-scheduler/*.jar:/opt/software/hive-2.3.3/lib/*' -Djava.library.path=:/opt/software/hadoop-2.8.3/lib/native org.apache.flume.node.Application --conf-file /opt/software/flume-1.8.0/conf/hdfs.conf --name agent1 Dflume.root.logger=DEBUG,console SLF4J: Class path contains multiple SLF4J bindings.

这个错误是由于在classpath中包含了多个SLF4J的绑定引起的。由于SLF4J提供了多种绑定，如果在classpath中包含了多个绑定，就会导致这个异常。为了解决这个问题，你可以在classpath中保留一个绑定，并删除其他绑定。或者你可以通过在classpath中包含一个名为slf4j-over-log4j的JAR来解决这个问题，它可以将所有SLF4J日志记录器路由到Log4J日志记录器。
