Chukwa0.4.0详细安装流程.docx

Chukwa 0.4.0 详细安装流程 1.安装好hadoop，确保hadoop运行无误（我hadoop版本为0.20.2）?2.去官网上下载chukwa 0.4.0版本：/dyn/closer.cgi/hadoop/chukwa/chukwa-0.4.0?3.下载后别急着分发到各个节点，因为代码中存在着一个bug，这个bug会影响后面hicc的显示，所以需要经过修改编译以后再将其分发到各个节点上比较好！修改编译具体过程如下：（1）源代码中找到ViewStore.java（package org.apache.hadoop.chukwa.datastore）在函数JSONArray list(String uid) 中，大概210行左右修改：FileStatus[] fstatus = fs.listStatus(viewFile);???????? if(fstatus!=null) {?????????? for(int i=0;ifstatus.length;i++) {+??????????? if(!fstatus[i].getPath().getName().endsWith(.view)) {+????????????? continue;+??????????? }???????????? long size = fstatus[i].getLen();???????????? FSDataInputStream viewStream = fs.open(fstatus[i].getPath());???????????? byte[] buffer = new byte[(int)size];（2）然后在$CHUKWA_HOME/输入ant，重新编译会在$CHUKWA_HOME/build/目录下得到编译后的文件（3）将$CHUKWA_HOME/build/chukwa-core-0.4.0.jar 拷贝到$CHUKWA_HOME，将$CHUKWA_HOME/build/chukwa.war拷贝到$CHUKWA_HOME/webapps当中?4.配置各个节点的环境变量，最好在~/.bash_profile当中配好，下面是我的配置：export JAVA_HOME=/usr/java/jdk1.6.0_16export JRE_HOME=/usr/java/jdk1.6.0_16/jreexport HADOOP_VERSION=0.20.2export HADOOP_HOME=/home/hadoop/hadoop-${HADOOP_VERSION}export CHUKWA_HOME=/home/zhangliuhang/chukwa/export ANT_HOME=/usr/ant/ant-1.7.0export PATH=.:$PATH: $JAVA_HOME/bin:$HADOOP_HOME/bin:$CHUKWA_HOME/bin:$ANT_HOME/bin?export CLASSPATH=$CLASSPATH:$JAVA_HOME/lib:$JRE_HOME/lib:$ANT_HOME/lib:$HADOOP_HOME/hadoop-${HADOOP_VERSION}-core.jar:$HADOOP_HOME/lib/*:$HADOOP_HOME/lib/commons-logging-1.0.4.jar:$ANT_HOME/junit-3.8.1.jar:$HADOOP_HOME/ivy/ivy-2.0.0-rc2.jar:$HADOOP_HOME/lib/commons-logging-api-1.0.4.jar:$HADOOP_HOME/lib/log4j-1.2.15.jar:$HADOOP_HOME/lib/hadoop-lzo-0.4.8.jar?export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib:/home/hadoop/hadoop-0.20.2/lib/native/Linux-amd64-64export JAVA_LIBRARY_PATH=/home/hadoop/hadoop-0.20.2/lib/native/Linux-amd64-64?export javalibpath=/home/hadoop/hadoop-0.20.2/lib/native/Linux-amd64-64?5.配置$CHUKWA_HOME/conf/chukwa-env.sh文件,其中的我的配置如下：（我只列出了没有被我注释掉的）export JAVA_HOME=/usr/java/jdk1.6.0_16export HADOOP_HO
