hue 用户权限分配

一世执手 提交于 2019-12-25 02:55:27
hue 用户权限分配 一、问题背景 CDH集群原来在使用hue部署oozie工作流的时候发现不能够运行工作流,因为当时hue创建用户时设置root为初始用户,而root用户不属于supergroup组,不能够调用集群中任何组件,为了解决这个问题,当时查参考了 CDH权限不够,修改用户和用户组为root 这篇文章的做法后面来看,只是治标不治本,并没有完全解决后面hue中如果设置其他用户后,其他用户所具有的权限问题,也没有深入讲解CDH组件用户权限问题。 今天这篇文章讲解的几个点 : 如何将集群内部组件恢复到原来的设置,并且让现在拥有的root用户继续能够调用工作流 在hue中添加新的用户,并让新的用户具有调用其他组件的权限 那个用户才是hue默认的初始用户 二 、恢复集群默认设置 1. 各个组件目录所属用户以及权限恢复到默认 /var/log 目录下涉及目录所属用户修改 sudo chown -R hdfs:hadoop /var/log/hadoop-hdfs sudo chown -R mapred:hadoop /var/log/hadoop-mapreduce sudo chown -R yarn:hadoop /var/log/hadoop-yarn sudo chown -R httpfs:httpfs /var/log/hadoop-httpfs sudo chown

问题 In the HUE Solr UI, there is an option to create a Dashboard to Search on an index. The search Field allows auto fill of the Index fieldsNames (as per the below HTML Snippet), but not autofill of Search Terms from the Index of the existing terms. HTML Code for the Search Box - <input data-bind="clearable: q, typeahead: { target: q, source: $root.collection.template.fieldsNames, multipleValues: true, multipleValuesSeparator: ':', extraKeywords: 'AND OR TO', completeSolrRanges: true } Is there

问题 I have the following MonoTouch code which can change the Saturation , but I am trying to also change the Hue . float hue = 0; float saturation = 1; if (colorCtrls == null) colorCtrls = new CIColorControls() { Image = CIImage.FromCGImage (originalImage.CGImage) }; else colorCtrls.Image = CIImage.FromCGImage(originalImage.CGImage); colorCtrls.Saturation = saturation; var output = colorCtrls.OutputImage; var context = CIContext.FromOptions(null); var result = context.CreateCGImage(output, output

说在前面的话   我的机器是总共4台,分别为 ubuntucmbigdata1、ubuntucmbigdata2、ubuntucmbigdata3和ubuntucmbigdata4。(注意啦,以下是针对Ubuntu系统的)   在 ubuntucmbigdata1 上执行了 sudo apt-get install cloudera-manager-daemons cloudera-manager-server sudo apt-get install cloudera-manager-daemons cloudera-manager-agent   即,ubuntucmbigdata1是既做server,又做agent。   在 ubuntucmbigdata2、ubuntucmbigdata3和ubuntucmbigdata4 上执行了 sudo apt-get install cloudera-manager-daemons cloudera-manager-agent   即,ubuntucmbigdata2、3、和4是只做agent。   在ubuntucmbigdata1、ubuntucmbigdata2、ubuntucmbigdata3、ubuntucmbigdata4上 新建文件 sudo vi /etc/apt/sources.list.d/cloudera

Hue安装 关于Hue的编译和安装详见我的另一片博客: https://blog.csdn.net/DataIntel_XiAn/article/details/103543368 配置Hue [hbase] hbase_clusters=(Cluster|hadoop:9090) hbase_conf_dir=/home/hadoop/hbase/conf 启动测试 首先应保证thrift服务启动( hbase-daemon.sh start thrift ),查看HBase数据发现连接超时,原因不知,参考 hbase.regionserver.thrift.framed Description Use Thrift TFramedTransport on the server side. This is the recommended transport for thrift servers and requires a similar setting on the client side. Changing this to false will select the default transport, vulnerable to DoS when malformed requests are issued due to THRIFT-601. Default false

Seaborn入门系列(二)——barplot&countplot&pointplot

微信公众号:易执 如有问题或建议,请公众号留言 Seaborn是基于matplotlib的Python可视化库。 它提供了一个高级界面来绘制有吸引力的统计图形。Seaborn其实是在matplotlib的基础上进行了更高级的API封装,从而使得作图更加容易,不需要 经过大量的调整就能使你的图变得精致。 注:所有代码均在IPython notebook中实现 barplot(条形图) 条形图表示数值变量与每个矩形高度的中心趋势的估计值,并使用误差线提供关于该估计值附近的不确定性的一些指示。具体用法如下: seaborn.barplot(x=None, y=None, hue=None, data=None, order=None, hue_order=None, estimator=(function mean), ci=95, n_boot=1000, units=None, orient=None, color=None, palette=None, saturation=0.75, errcolor='.26', errwidth=None, capsize=None, dodge=True, ax=None, **kwargs) 接下来还是通过具体例子学习里面的一些参数的用法: %matplotlib inline import pandas as pd import
