做火花壳MLIB，错误：对象jblas不是包的成员组织 [英] doing spark-shell with mlib, error: object jblas is not a member of package org

问题描述

在火花壳，当我exectue 进口org.jblas.DoubleMatrix ，它会抛出错误：对象jblas不包组织成员在RHEL

In spark-shell, when I exectue import org.jblas.DoubleMatrix, it will throw "error: object jblas is not a member of package org" on the RHEL.

其实，我用Google搜索有关从 https开头jblas并安装gfortran：// GCC。在我的Mac Pro gnu.org/wiki/GFortranBinaries#MacOS 。

Actually, I googled about "jblas" and installed "gfortran" from https://gcc.gnu.org/wiki/GFortranBinaries#MacOS on my mac pro.

我的火花版本是火花1.4.0彬hadoop2.6.tar或火花1.5.1彬hadoop2.6.tar，这是直接从官方网站上下载，这是说，我没'T从源头code构建。

My spark version is spark-1.4.0-bin-hadoop2.6.tar or spark-1.5.1-bin-hadoop2.6.tar, which is download directly from the official website, it's to say that I didn't build from the source code.

推荐答案

这一步是可选的，它会在你的笔记本电脑存储库安装jblas罐子。

This step may be optional, it will install the jblas jar on your laptop repository.

git clone https://github.com/mikiobraun/jblas.git
cd jblas
mvn install

输入到火花目录

cd /Users/erichan/Garden/spark-1.5.1-bin-cdh4

启动与封装选项的火花外壳，如果你没有做的第一步，你应该给予正确的Maven坐标jblas：

Launch the spark shell with packages option, and if you didn't do the first step, you should give the right maven coordinate for jblas:

bin/spark-shell --name my_mlib --packages org.jblas:jblas:1.2.4-SNAPSHOT --driver-memory 4G --executor-memory 4G --driver-cores 2
