Snappy data compression configuration to Hadoop

Dependent Library: yum-y Install gcc+ gcc-c++

The compiler prerequisites are mentioned in the official documentation: GCC C + +, autoconf, Automake, Libtool, Java 6, Java_home set, Maven 3

1: Download the required dynamic library and Hadoop snappy plug-in project

snappy-1.1.2.tar.gz Dynamic Library

Source-archive Maven Jar

2: Compile snappy-1.1.2.tar.gz (gcc g++, etc.)

./configure
Make
Make install

It worked. There are dynamic library files under Usr/local/lib

Problems encountered:

MVN Package
Error:could not find or Load main class Org.codehaus.plexus.classworlds.launcher.Launcher

Because the MAVEN environment did not import execution: Export M2_home=/usr/share/maven export path= $PATH: $M 2_home/bin

Subsequently compiled: MVN package

Problems encountered:

Cannot run Program "autoreconf" installs the dependent libraries mentioned above

Cannot FIND-LJVM this error because the libjvm.so that installed the JVM was not linked to/usr/local/lib. If your system is AMD64, you can do the following to solve the problem:

ln -s /usr /java/jdk17.0_75/jre/lib/amd64/ server/libjvm.< Span class= "crayon-v" >so /usr /local/lib/

< Span class= "crayon-v" > < Span class= "Crayon-o" > < Span class= "crayon-v" > then get the compilation Successful jar
