我也是服了,为啥把我的回答删掉了。楼主这个问题我已经解决了
原因是因为版本冲突问题
升级springCloud版本即可

        <spring.boot.version>2.1.2.RELEASE</spring.boot.version>
        <spring.cloud.version>Greenwich.RELEASE</spring.cloud.version>

我用的是 2.1.2 当然 Greenwich 支持 所有 2.1.*

重新启动hadoop失败 webapps/hdfs not found in CLASSPATH

最近需要在16节点配置hbase 环境:hadoop2.6+zookeeper3.4.6+hbase0.98.9 ubuntu12.04 server 64bit jdk 1.8.0_11 hadoop 配置的1个namenode和15个datanode zookeeper配置的3台 hbase一个Hmaster15个HRegion 开始时配置没问题,在hbase上跑东西也没问题 需要改变节点数量,所以关闭hbase,然后关闭zookeeper,最后关闭hadoop集群 不过我没有format那个hadoop的namenode 然后我就遇到hadoop的namenode起不起来的问题 请问有没有人对这个问题有研究啊? 我看hdfs的启动日志写的是: java.io.FileNotFoundException: webapps/hdfs not found in CLASSPATH 在网上也没看到类似问题和解决方案 怀疑是hbase集群关闭时是不是需要format 或者配置文件哪里不对 我查了关于classpath的hadoop配置文件,只有一个Yarn-site.xml的yarn.application.classpath那个我是注释掉的,应该也不是这个问题的吧 尝试重新format过namenode节点,重启还是不行 尝试过重新把hadoop删掉重新配置,不行 尝试改hdfs的启动脚本,在运行时手动export加上webapps/hdfs文件夹,不行 请问各位有没有解决办法啊?或者这个问题的大致思路? 启动日志如下:${HADOOP_HOME}//ogs/hadoop-ubuntu-namenode-m1.log ``` 2015-02-01 22:45:43,870 INFO org.apache.hadoop.hdfs.server.namenode.NameNode: STARTUP_MSG: /************************************************************ STARTUP_MSG: Starting NameNode STARTUP_MSG: host = m1/172.18.9.100 STARTUP_MSG: args = [] STARTUP_MSG: version = 2.2.0 STARTUP_MSG: classpath = /home/ubuntu/hadoop/hadoop-2.6.0/etc/hadoop:/home/ubuntu/hadoop/hadoop-2.6.0/share/hadoop/common/lib/asm-3$ STARTUP_MSG: build = https://svn.apache.org/repos/asf/hadoop/common -r 1529768; compiled by 'hortonmu' on 2013-10-07T06:28Z STARTUP_MSG: java = 1.8.0_11 ************************************************************/ 2015-02-01 22:45:43,887 INFO org.apache.hadoop.hdfs.server.namenode.NameNode: registered UNIX signal handlers for [TERM, HUP, INT] 2015-02-01 22:45:44,515 INFO org.apache.hadoop.metrics2.impl.MetricsConfig: loaded properties from hadoop-metrics2.properties 2015-02-01 22:45:44,670 INFO org.apache.hadoop.metrics2.impl.MetricsSystemImpl: Scheduled snapshot period at 10 second(s). 2015-02-01 22:45:44,671 INFO org.apache.hadoop.metrics2.impl.MetricsSystemImpl: NameNode metrics system started 2015-02-01 22:45:50,066 INFO org.mortbay.log: Logging to org.slf4j.impl.Log4jLoggerAdapter(org.mortbay.log) via org.mortbay.log.Slf4j$ 2015-02-01 22:45:50,069 INFO org.apache.hadoop.metrics2.impl.MetricsSystemImpl: Stopping NameNode metrics system... 2015-02-01 22:45:50,070 INFO org.apache.hadoop.metrics2.impl.MetricsSystemImpl: NameNode metrics system stopped. 2015-02-01 22:45:50,070 INFO org.apache.hadoop.metrics2.impl.MetricsSystemImpl: NameNode metrics system shutdown complete. 2015-02-01 22:45:50,071 FATAL org.apache.hadoop.hdfs.server.namenode.NameNode: Exception in namenode join **java.io.FileNotFoundException: webapps/hdfs not found in CLASSPATH **** at org.apache.hadoop.http.HttpServer.getWebAppsPath(HttpServer.java:585) at org.apache.hadoop.http.HttpServer.<init>(HttpServer.java:251) at org.apache.hadoop.http.HttpServer.<init>(HttpServer.java:174) at org.apache.hadoop.hdfs.server.namenode.NameNodeHttpServer$1.<init>(NameNodeHttpServer.java:76) at org.apache.hadoop.hdfs.server.namenode.NameNodeHttpServer.start(NameNodeHttpServer.java:74) at org.apache.hadoop.hdfs.server.namenode.NameNode.startHttpServer(NameNode.java:626) at org.apache.hadoop.hdfs.server.namenode.NameNode.initialize(NameNode.java:488) at org.apache.hadoop.hdfs.server.namenode.NameNode.<init>(NameNode.java:684) at org.apache.hadoop.hdfs.server.namenode.NameNode.<init>(NameNode.java:669) at org.apache.hadoop.hdfs.server.namenode.NameNode.createNameNode(NameNode.java:1254) at org.apache.hadoop.hdfs.server.namenode.NameNode.main(NameNode.java:1320) 2015-02-01 22:45:50,075 INFO org.apache.hadoop.util.ExitUtil: Exiting with status 1 2015-02-01 22:45:50,078 INFO org.apache.hadoop.hdfs.server.namenode.NameNode: SHUTDOWN_MSG: /************************************************************ SHUTDOWN_MSG: Shutting down NameNode at m1/172.18.9.100 ************************************************************/ ```

The Best Path

Problem Description Alice is planning her travel route in a beautiful valley. In this valley, there are N lakes, and M rivers linking these lakes. Alice wants to start her trip from one lake, and enjoys the landscape by boat. That means she need to set up a path which go through every river exactly once. In addition, Alice has a specific number (a1,a2,...,an) for each lake. If the path she finds is P0→P1→...→Pt, the lucky number of this trip would be aP0XORaP1XOR...XORaPt. She want to make this number as large as possible. Can you help her? Input The first line of input contains an integer t, the number of test cases. t test cases follow. For each test case, in the first line there are two positive integers N (N≤100000) and M (M≤500000), as described above. The i-th line of the next N lines contains an integer ai(∀i,0≤ai≤10000) representing the number of the i-th lake. The i-th line of the next M lines contains two integers ui and vi representing the i-th river between the ui-th lake and vi-th lake. It is possible that ui=vi. Output For each test cases, output the largest lucky number. If it dose not have any path, output "Impossible". Sample Input 2 3 2 3 4 5 1 2 2 3 4 3 1 2 3 4 1 2 2 3 2 4 Sample Output 2 Impossible

玩转springboot启动banner定义所得

最近接手了一个springboot项目,不是不熟悉这个框架,启动时打印的信息吸引了我。 这不是我熟悉的常用springboot的打印信息啊,我打开自己的项目: 还真是的,不用默认的感觉也挺高大上的。一时兴起,就去研究了一下源代码,还正是有些收获,稍后我会总结一下。正常情况下做为一个老程序员,是不会对这种小儿科感兴趣的,不就是一个控制台打印嘛。哈哈! 于是出于最初的好奇,研究了项目的源代码。看到

离职半年了,老东家又发 offer,回不回?

有小伙伴问松哥这个问题,他在上海某公司,在离职了几个月后,前公司的领导联系到他,希望他能够返聘回去,他很纠结要不要回去? 俗话说好马不吃回头草,但是这个小伙伴既然感到纠结了,我觉得至少说明了两个问题:1.曾经的公司还不错;2.现在的日子也不是很如意。否则应该就不会纠结了。 老实说,松哥之前也有过类似的经历,今天就来和小伙伴们聊聊回头草到底吃不吃。 首先一个基本观点,就是离职了也没必要和老东家弄的苦...

当HR压你价,说你只值7K,你该怎么回答?

当HR压你价,说你只值7K时,你可以流畅地回答,记住,是流畅,不能犹豫。 礼貌地说:“7K是吗?了解了。嗯~其实我对贵司的面试官印象很好。只不过,现在我的手头上已经有一份11K的offer。来面试,主要也是自己对贵司挺有兴趣的,所以过来看看……”(未完) 这段话主要是陪HR互诈的同时,从公司兴趣,公司职员印象上,都给予对方正面的肯定,既能提升HR的好感度,又能让谈判气氛融洽,为后面的发挥留足空间。...

无代码时代来临,程序员如何保住饭碗?

编程语言层出不穷,从最初的机器语言到如今2500种以上的高级语言,程序员们大呼“学到头秃”。程序员一边面临编程语言不断推陈出新,一边面临由于许多代码已存在,程序员编写新应用程序时存在重复“搬砖”的现象。 无代码/低代码编程应运而生。无代码/低代码是一种创建应用的方法,它可以让开发者使用最少的编码知识来快速开发应用程序。开发者通过图形界面中,可视化建模来组装和配置应用程序。这样一来,开发者直...

《经典算法案例》01-08:如何使用质数设计扫雷(Minesweeper)游戏

我们都玩过Windows操作系统中的经典游戏扫雷(Minesweeper),如果把质数当作一颗雷,那么,表格中红色的数字哪些是雷(质数)?您能找出多少个呢?文中用列表的方式罗列了10000以内的自然数、质数(素数),6的倍数等,方便大家观察质数的分布规律及特性,以便对算法求解有指导意义。另外,判断质数是初学算法,理解算法重要性的一个非常好的案例。
