Hive on spark查询报错。

求助！！！在hadoop使用Hive on spark执行Bigbench测试时，一直会有报错，log信息： FAILED: SemanticException Failed to get a spark session: org.apache.hadoop.hive.ql.metadata.HiveException: Failed to create spark client. WARN: The method class org.apache.commons.logging.impl.SLF4JLogFactory#release() was invoked. WARN: Please see http://www.slf4j.org/codes.html#release for an explanation. An error occured while running command: ========== runEngineCmd -f /var/lib/hadoop-hdfs/Big-Bench/engines/hive/queries/q04/q04.sql ========== 在网上查了很多资料，有说版本不匹配的，有说是概率性问题，有没有大佬来瞅一眼啊。。哭了

**之前改过一次主机名，修改了etc/hosts和 etc/sysconfig/network里的hostname， hadoop的core-site.xml中也做出相应修改， 但用hive命令启动后，报错：** ``` Exception in thread "main" java.lang.IllegalArgumentException: java.net.UnknownHostException: hadoop000 at org.apache.hadoop.security.SecurityUtil.buildTokenService(SecurityUtil.java:374) at org.apache.hadoop.hdfs.NameNodeProxies.createNonHAProxy(NameNodeProxies.java:310) at org.apache.hadoop.hdfs.NameNodeProxies.createProxy(NameNodeProxies.java:176) at org.apache.hadoop.hdfs.DFSClient.<init>(DFSClient.java:708) at org.apache.hadoop.hdfs.DFSClient.<init>(DFSClient.java:651) at org.apache.hadoop.hdfs.DistributedFileSystem.initialize(DistributedFileSystem.java:149) at org.apache.hadoop.fs.FileSystem.createFileSystem(FileSystem.java:2696) at org.apache.hadoop.fs.FileSystem.access$200(FileSystem.java:94) at org.apache.hadoop.fs.FileSystem$Cache.getInternal(FileSystem.java:2733) at org.apache.hadoop.fs.FileSystem$Cache.get(FileSystem.java:2715) at org.apache.hadoop.fs.FileSystem.get(FileSystem.java:382) at org.apache.hadoop.fs.FileSystem.get(FileSystem.java:181) at org.apache.hadoop.hive.ql.session.SessionState.start(SessionState.java:583) at org.apache.hadoop.hive.ql.session.SessionState.beginStart(SessionState.java:553) at org.apache.hadoop.hive.cli.CliDriver.run(CliDriver.java:750) at org.apache.hadoop.hive.cli.CliDriver.main(CliDriver.java:686) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:498) at org.apache.hadoop.util.RunJar.run(RunJar.java:221) at org.apache.hadoop.util.RunJar.main(RunJar.java:136) Caused by: java.net.UnknownHostException: hadoop000 ... 22 more ``` hadoop000是我之前的主机名，搞不明白hive是在哪个配置文件里读到的，所以无从下手修改，求助各位大佬，感激不尽！！

kettle生产环境hive到mysql连接出错

1.kettle做数据转换 从hive到mysql，本地spoon.bat开发运行正常，上传到linux下用kitchen.sh执行不报错但是会卡住，debug模式下日志如图。 2.做了单个测试，job转换中只连接mysql执行个查询可以，或者只连接hive执行查询语句也可以。但是同时将两个步骤放到一个转换里 就出现跟上面一样的问题  na位路过的大佬帮忙看下。

datax从hive导出数据到mysql

从MySQL导入数据到hive上是没问题的，从hive上导出数据时，提示： [您的配置错误.]. - 列配置信息有错误. 因为您配置的任务中，源头读取字段数:1 与 目的表要写入的字段数:4 不相等. 请检查您的配置并作出修改. 下面是我的json文件： ```{ "job": { "content": [{ "reader": { "parameter": { "path": "/apps/hive/warehouse/test.db/job01", "column": ["*"], "defaultFS": "hdfs://xxxx.xx.xx:8020", "encoding": "utf-8", "fieldDelimiter": "\u0001", "fileType": "text" }, "name": "hdfsreader" }, "writer": { "parameter": { "password": "*****", "column": ["*"], "connection": [{ "jdbcUrl": "jdbc:mysql://xxxxx:3308/groundcherry", "table": ["scoop_test"] }], "writeMode": "insert", "username": "****" }, "name": "mysqlwriter" } }], "setting": { "speed": { "channel": 1 } } } } ``` 网上说是分割符的问题，使用默认的 \u0001，导入的时候可以导入进去，导出的时候就报错了，使用","号也是一样，hive上建表时指定的字段分隔符与这个是一致的，有点怀疑是不是字段分割的原因，还会有什么原因导致这种错误呢，请大家指点指点谢谢

Hive执行SQL语句报错hive> show databases; ----已解决

``` hive> show databases; FAILED: SemanticException org.apache.hadoop.hive.ql.metadata.HiveException: java.lang.RuntimeException: Unable to instantiate org.apache.hadoop.hive.ql.metadata.SessionHiveMetaStoreClient hive> ``` 百度了很多，都是下面的解决方法 ``` 修改hive的配置文件hive-site.xml <property> <name>datanucleus.schema.autoCreateAll</name> <value>true</value> </property> 然后删除MySQL中原来的表 drop database hive_metastore; 重新初始化元数据 schematool -dbType mysql -initSchema ``` 按照上面的操作执行后，还是报相同的错误 请问，这个如何解决？ 已解决：在多次挣扎后，我尝试了网上很多的方法，但都没有成功；经过多次修改与测试，最终终于找到了问题所在，原来只是java的版本出现的问题，与hive的版本不匹配，我开始使用的是java的最新版jdk-10.0.2,我开始的想法是高版本的能兼容低版本，后来验证我的想法是错的，我将java换成jdk8后，嘿，一下子就可以了，哎，怪我没有好好的认真看一下官方的文档，浪费了我两天的时间啊。

datax 从hive导出数据到mysql时 字段分隔符的配置

hive中建表时指定字段分割符为 \t，配置导出的json时，配置字段分隔符为 \t，导出失败，原因是从hive读取数据时只能识别一个字段，显然字段分割没有成功。。网上百度说字段分隔符默认应设置为 \u0001,但这是在hive上建表时没有指定字段分割符时。。想搞明白这是什么原因，比如我的 \t 在导出时为什么不能使用呢，是hive无法识别吗？我建表的时候就是 \t 啊，是需要转成什么字符集吗。。在字符集这块比较晕，请大神指点指点[face]qq:83.gif[/face]

hive 设置开启事务功能，运行报错

现在想实现hive的删除和修改功能，hive版本1.2。 但是配置了好久总是报错，求大神们指点。 按照网上帖子配置了hive-site.xml ``` <property> <name>hive.support.concurrency</name> <value>true</value> </property> <property>

<property> <name>hive.compactor.initiator.on</name> <value>true</value> </property> <property> <name>hive.compactor.worker.threads</name> <value>1</value> </property> ``` 也在元数据里面加入了以下表和数据 ``` INSERT

我花了一夜用数据结构给女朋友写个H5走迷宫游戏

起因 又到深夜了，我按照以往在csdn和公众号写着数据结构！这占用了我大量的时间！我的超越妹妹严重缺乏陪伴而 怨气满满！ 而女朋友时常埋怨，认为数据结构这么抽象难懂的东西没啥作用，常会问道：天天写这玩意，有啥作用。而我答道：能干事情多了，比如写个迷宫小游戏啥的！ 当我码完字准备睡觉时：写不好别睡觉！ 分析 如果用数据结构与算法造出东西来呢？ ...

究竟你适不适合买Mac？

Linux(内核剖析):19---中断总体概述

一、为什么要引入中断？ 任何操作系统内核的核心任务，都包含有对连接到计算机上的硬件设备进行有效管理，如硬盘、蓝光碟机、键盘、鼠标、3D 处理器，以及无线电等。而想要管理这些设备，首先要能和它们互通音信才行。众所周知，处理器的速度跟外围硬件设备的速度往往不在一个数量级上，因此，如果内核采取让处理器向硬件发出一个请求，然后专门等待回应的办法，显然差强人意。既然硬件的响应这么慢，那么内核就应该在此期间...

智力题（程序员面试经典）
