在hive中不能使用。/bin/hdfs创建文件

是的,Hive不支持使用`/bin/hdfs`命令来创建文件。Hive是一个基于Hadoop的数据仓库工具,它使用Hadoop分布式文件系统(HDFS)来存储和管理数据。在Hive中,您可以使用HiveQL语言来执行查询和管理数据,但是不能像在Linux终端中一样使用命令行来创建文件。如果您想在HDFS中创建文件,可以使用Hadoop的命令行工具,例如`hdfs dfs -touchz <filename>`来创建一个空文件。

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。

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。
