CDH4主要用于YARN吗? [英] Is CDH4 meant mainly for YARN?

问题描述

关于CDH4，我有几个问题甚至是困惑.我之所以张贴在这里，是因为我没有得到关于我的问题的任何具体信息.

I have several questions or rather confusions regarding CDH4. I am posting here since I did not get any concrete information regarding my questions.

CDH4是否旨在促进YARN?我尝试使用tarball使用CDH4.3.0设置MapReduce1.我终于做到了，但是这很痛苦.而YARN的建立是遥遥领先的.

Is CDH4 meant to promote YARN? I tried setting up MapReduce1 using CDH4.3.0 using tarball. I finally did but it is round about and painful. Whereas YARN set up is strait forward.

有人在生产中使用YARN吗? Apache明确表示YARN仍为Alpha版本，并不打算用于生产.在这种情况下，Cloudera为什么以CDH4 YARN为中心? Cloudera在生产中是否支持YARN?

Is anyone using YARN in production at all? Apache clearly says that YARN is still in alpha version and not meant for production. In such cases why is Cloudera making CDH4 YARN centric? Does Cloudera support YARN in production?

如果问题不合适，我们深表歉意.

Apologies if the questions are inappropriate.

推荐答案

不，CDH4并非主要用于YARN.另一方面，将是CDH5.

No, CDH4 is not meant mainly for YARN. CDH5, on the other hand, will be.

我不确定您如何设置CDH集群，但是使用Cloudera Manager相对于YARN而言，添加MapReducev1服务相当容易.

I'm not sure how you went about setting up your CDH cluster, but it's rather easy to add the MapReducev1 service, as opposed to YARN, using Cloudera Manager.

很少有公司在生产中使用YARN，其中最引人注目的是Yahoo.

Very few companies use YARN in production, Yahoo being the most notable.

CDH4不是以YARN为中心的. Cloudera包含YARN，因此人们可以访问他们的最新Hadoop位-但是在Cloudera的网站上很清楚，他们不建议将YARN用于生产.

CDH4 is not YARN-centric. Cloudera includes YARN so people can have the most recent Hadoop bits accessible to them - but it's very clear on Cloudera's website that they do not recommend YARN for production.

CDH4去年问世的一大事情是HDFSv2，它们使MRv1与之兼容.

One of the big things that CDH4 brought to the table last year was HDFSv2, and they made MRv1 compatible with it.

要使用MRv1安装CDH4，请参见
