Java Namenode未运行

java linux jakarta-ee hadoop hbase

Java Namenode未运行,java,linux,jakarta-ee,hadoop,hbase,Java,Linux,Jakarta Ee,Hadoop,Hbase,在完成hadoop的设置之后，当我尝试运行hadoop时，我发现（通过jps）namenode没有运行。我在日志文件中搜索，发现一个异常：“目录/hadoop/tmp/dfs/name处于不一致状态：存储目录不存在或不可访问。”。因此，我通过sudomkdir-p/hadoop/tmp/dfs/name在/hadoop/tmp/dfs/name中创建了I目录，并赋予了这个完整的权限。现在，在重新启动hadoop之后，我看到namenode仍然没有发出隆隆声，我发现这个异常“dFSNamesyst

在完成hadoop的设置之后，当我尝试运行hadoop时，我发现（通过jps）namenode没有运行。我在日志文件中搜索，发现一个异常：“目录/hadoop/tmp/dfs/name处于不一致状态：存储目录不存在或不可访问。”。因此，我通过sudomkdir-p/hadoop/tmp/dfs/name在/hadoop/tmp/dfs/name中创建了I目录，并赋予了这个完整的权限。现在，在重新启动hadoop之后，我看到namenode仍然没有发出隆隆声，我发现这个异常“dFSNamesystem初始化失败。java.io.IOException:namenode未格式化”。我已经格式化了namenode“{hadoop dir}/bin hadoop namenode-format”，它的格式很好，但namenode日志中仍然存在异常。下面给出了我的namenode日志
