Hadoop HDFS： the directory item limit is exceed: limit=1048576问题的解决

2017-11-06 745

问题描述：

1.文件无法写入hadoop hdfs文件系统；

2.hadoop namenode日志记录

 
        the directory item limit is exceed: limit=1048576

3.hadoop单个目录下文件超1048576个，默认limit限制数为1048576，所以要调大limit限制数

解决办法：

 
        hdfs-site.xml配置文件添加配置参数
       
        <property>
       
        <name>dfs.namenode.fs-limits.max-directory-items<
        /name
        > 
       
        <value>3200000<
        /value
        > 
       
        <description>Defines the maximum number of items that a directory may 
       
        contain. Cannot 
        set 
        the property to a value 
        less 
        than 1 or 
        more 
        than 
       
        6400000.<
        /description
        > 
       
        <
        /property
        > 
       
        将配置文件推送至hadoop集群所有节点
       
        重启hadoop服务

hadoop hdfs jvm内存溢出，无法成功启动

默认启动-Xmx1000m

解决办法：

由于cdh yum安装默认无hadoop-env.sh文件，添加hadoop-env.sh文件，并增加环境参数

 
        export 
        HADOOP_HEAPSIZE=32000

问题解决！

安装PredictionIO

PredictionIO：安装官方地址：http://docs.prediction.io/install/install-linux/ 安装PredictionIO必需安装好java。注意：很多时候安装PredictionIO时会提示：JAVA_HOME 相关的错误，基本上是java版本不对或没有安装。查看是否有安装 java：安装java: 要求是：【Java SE Development Kit 7】即开发工具包，如果已经安装了可以跳过。最好安装 java-jdk-8 及以上稳定性会更高。下载地址：http://www.oracle.com/technetwork/java/javase/downloads/index.html 下载rpm包 rpm -ivh jdk-8u45-linux-x64.rpm 注意：Ubuntu（或基于Debian文件系统）的linux系统不能直接使用rpm 主要是因为Ubuntu的软件包格式是deb，如果要安装rpm包，得把rpm转换成deb，可以使用alien转换工具然后使用dpkg安装，但成功率不高，可以直接下载java的压缩免安...

Hive MapJoin OOM

Hive升级完后ETL开发找到我说有的Job一直failed.看了一下在MAP阶段进行MAPJOIN处理时就OOM了，但是开发说没有加MAPJOIN HINT,其实在0.11后hive.auto.convert.join的默认值变为true也就是会自动去做；并且在0.11加入了一个新的参数hive.ignore.mapjoin.hint来控制是否忽略MAPJOINHINT(HIVE-4042),默认也是true，即使加了默认也会被忽略掉的. 不过对于MAPJOIN对于内存的消耗确实非常高，基本要3X-4X数据量（具体见HIVE-6430），其中HIVE-6418,HIVE-6429都有一定的修复(分别针对MAPJOINKEY,MAPJOINROWCONTAINER)，不过是在0.13了. 本文转自MIKE老毕 51CTO博客，原文链接：http://blog.51cto.com/boylook/1366330，如需转载请自行联系原作者
