无法构建fuse-dfs来挂载HDFS [英] Not able to build fuse-dfs to mount HDFS

问题描述

我的Hadoop版本是2.5.2。

我想用保险丝装载Hadoop。我尝试了两种方法，但都失败了。一种方法是：

  HADOOP_HOME：ant compile-c ++  -  libhdfs -Dlibhdfs = 1`。 
  

但它无法找到 build.xml 。另一种方法是在 hadoop-hdfs / target / native / main / native / fuse-dfs 中，我执行 make 但仍然没有fuse-dfs。

我应该如何构建fuse-dfs，以便我可以通过保险丝挂载HDFS？

  $ mvn包-Pnative -Drequire.fuse = true -DskipTests -Dmaven.javadoc.skip = true 
  

这条指令在稍后的fuse-dfs的README文件中（hadoop-hdfs-project / hadoop-hdfs / src / main / native / fuse-dfs / doc / README）

BUILDING

<可以通过使用Maven将 require.fuse 选项设置为true来构建fuse-dfs可执行文件。例如：HADOOP_PREFIX中的
： mvn包-Pnative -Drequire.fuse = true -DskipTests -Dmaven.javadoc.skip = true

可执行文件 fuse_dfs 将位于HADOOP_PREFIX / hadoop-hdfs-project / hadoop-hdfs-native-client / target / main / native / fuse-dfs /

但2.5.2源代码指向较老的指令。

我的构建环境是CentOS 6服务器。我添加了 https://wiki.apache.org/hadoop/HowToContribute 中提到的其他软件包在本地库下：

对于RHEL（也就是CentOS）：

yum -y install lzo-devel zlib-devel gcc gcc -c ++ autoconf automake libtool openssl-devel fuse-devel cmake

My Hadoop version is 2.5.2.

I want to mount Hadoop with fuse. I have tried two methods, but both failed. One method is in:

HADOOP_HOME: ant compile-c++-libhdfs -Dlibhdfs=1`.

But it failed for it can't find build.xml. The other method is in hadoop-hdfs/target/native/main/native/fuse-dfs, I execute make but still don't have fuse-dfs.

How should I build fuse-dfs so I can mount HDFS by fuse?

解决方案

I'm assuming you already have Java and Maven installed and can build the other Hadoop components. After that you run:

$ mvn package -Pnative -Drequire.fuse=true -DskipTests -Dmaven.javadoc.skip=true

This instruction is in later READMEs for fuse-dfs (hadoop-hdfs-project/hadoop-hdfs/src/main/native/fuse-dfs/doc/README)

BUILDING

fuse-dfs executable can be built by setting require.fuse option to true using Maven. For example: in HADOOP_PREFIX: mvn package -Pnative -Drequire.fuse=true -DskipTests -Dmaven.javadoc.skip=true

The executable fuse_dfs will be located at HADOOP_PREFIX/hadoop-hdfs-project/hadoop-hdfs-native-client/target/main/native/fuse-dfs/

but the 2.5.2 source refers to the older instructions.

My build environment is a CentOS 6 server. I added the additional packages mentioned in https://wiki.apache.org/hadoop/HowToContribute under Native libraries:

For RHEL (and hence also CentOS):

yum -y install lzo-devel zlib-devel gcc gcc-c++ autoconf automake libtool openssl-devel fuse-devel cmake
