Fiware

Question

我正在尝试运行来自 http://forge.fiware.org/plugins/mediawiki/wiki/fiware/index.php/BigData_Analysis_-_User_and_Programmer_Guide

我卡在了线

"easy_install https://forge.fi-ware.org/frs/download.php/1309/cosmos-0.16.0-py2.7.egg"

系统打印输出：

Downloading https://forge.fi-ware.org/frs/download.php/1309/cosmos-0.16.0-py2.7.egg
Processing cosmos-0.16.0-py2.7.egg

cosmos 0.16.0 is already the active version in easy-install.pth
Installing cosmos script to /usr/bin

Installed /usr/lib/python2.6/site-packages/cosmos-0.16.0-py2.7.egg

Reading http://pypi.python.org/simple/cosmos/
No local packages or download links found for cosmos==0.16.0

但之后我意识到我使用的是来自conference 的image 和cosmos 应该安装，所以我运行

# cosmos

这是我的系统打印输出：

Traceback (most recent call last):
  File "/usr/bin/cosmos", line 5, in <module>
    from pkg_resources import load_entry_point

    needed = self.resolve(parse_requirements(requirements))
  File "/usr/lib/python2.6/site-packages/pkg_resources.py", line 546, in resolve
    raise DistributionNotFound(req)

如何正确运行 cosmos ??

Answer 1

为了在 FIWARE LAB 中访问已经部署的类 Hadoop Cosmos 实例，您不需要 Cosmos CLI；这是为了在类似 Hadoop 即服务的 Cosmos 部署上按需创建新集群，而 FIWARE LAB 不是这种情况。

只需转到 here 并使用您的 FIWARE LAB 凭据创建一个 Cosmos 帐户。然后，按照该网站中指出的步骤进行操作。

关于Cosmos documentation，请忽略第2.3节之前的第一节。
