由于libprotoc在Eclipse下使用Hadoop时，Trunk不会编译 [英] Trunk doesn't compile because libprotoc is old when working with Hadoop under Eclipse

问题描述

我正在关注使用Eclipse下的Hadoop，并尝试运行

I am following "working with Hadoop under Eclipse" and trying to run

$ mvn install -DskipTests

$ b $一段时间后，我收到一个错误：

After a while, I received an error:

[错误]执行目标无法执行org.apache.hadoop：hadoop- maven-plugins：3.0.0-SNAPSHOT：proc（compile-protoc）项目hadoop-common：org.apache.maven.plugin.MojoExecutionException：protoc版本是'libprotoc 2.4.1'，预期版本是'2.5.0' - > [帮助1]

[ERROR] Failed to execute goal org.apache.hadoop:hadoop-maven-plugins:3.0.0-SNAPSHOT:protoc (compile-protoc) on project hadoop-common: org.apache.maven.plugin.MojoExecutionException: protoc version is 'libprotoc 2.4.1', expected version is '2.5.0' -> [Help 1]

与此页面中报告的内容。

有谁知道如何解决？我应该如何升级libprotoc？

Does anyone know how to solve it? How should I do to upgrade libprotoc?

推荐答案

协议缓冲区用作不同守护进程之间的RPC协议。一些Linux版本没有所需的版本。因此，协议缓冲区代码必须从构建并安装的此处下载。这些是下载的软件包中README.txt的说明。

Protocol Buffers is used as an RPC protocol between different daemons. Some of the Linux releases don't have the required version. So, Protocol Buffers code has to be downloaded from here, built and installed. These are the instructions from the README.txt in the downloaded bundle.

To build and install the C++ Protocol Buffer runtime and the Protocol Buffer compiler (protoc) execute the following:

$ ./configure
$ make
$ make check
$ make install

If "make check" fails, you can still install, but it is likely that some features of this library will not work correctly on your system. Proceed at your own risk. "make install" may require superuser privileges.
