背景:我的是CDH6.2集群,安装成功时,都可以找到hive,直接查询,后面重启一次后,查询不到hive 解决: cd /etc/hue/conf vi hue.ini 找到beeswax标签 打开配置: ##hive_server_host=localhost ##hive_server_port=10000 ##hive_conf_dir=/etc/hive/conf 请根据个人的情况来设置 来源: CSDN 作者: 没有合适的昵称 链接: https://blog.csdn.net/weixin_42411818/article/details/103232957

Hadoop集群配置Hue

Hue是一个轻量级的Web服务器,可让您 直接从浏览器 使用Hadoop 。 Hue只是一个“在任何Hadoop发行版之上的视图”,可以安装在任何机器上。 官方文档在 官方文档 有多种方式(比如 gethue.com的 “下载”部分 )安装Hue。 下一步就是将Hue配置为指向您的 Hadoop集群 。 默认情况下,Hue假定存在一个本地集群(即只有一台机器)。 为了与真正的集群进行交互,Hue需要知道哪些主机分配了Hadoop服务。 hue.ini在哪里?(配置文件) hue主要配置发生在 hue.ini 文件中。 它列出了很多选项,但本质上什么是HDFS,YARN,Oozie,Hive的地址和端口...根据您安装的ini文件的分布位于: CDH 包: /etc/hue/conf/hue.ini tarball 版本: /usr/share/desktop/conf/hue.ini 开发版本: desktop/conf/pseudo-distributed.ini Cloudera Manager : CM 为你生成所有的hue.ini,所以没有麻烦? /var/run/cloudera-scm-agent/process/`ls -alrt /var/run/cloudera-scm-agent/process | grep HUE | tail -1 | awk ‘

R语言ggplot中的颜色

ggplot2分组时默认使用的颜色,可以从另一个hadley写的包,scales包中调用。这个包算是一个工具包,用于和hadley写的其他包配合使用,颜色是其中一部分。 library(scales) show_col(hue_pal()(3)) # show_col(hue_pal(h = c(0, 360) + 15, c = 100, l = 65)(3)) # 和上面一样,默认设置 hue_pal函数的默认设置,其中h是色相,范围越大,相邻颜色之间差异越大;c是饱和度,值越大色彩越浓艳饱满;l是亮度,大亮小暗。 柱状图的颜色搭配: colorbar <- function(values){ groupbar + scale_fill_manual(values = values) } colorlist <- list(c("#8FBC94","#548687"),c("#4FB0C6","#4F86C6"), c("#C65146","#EC6A5C"),c("#6E7783","#77AAAD"), c("#e97f02","#f8ca00"),c("#3a5134","#4f953b"), c("#99CCCC","#FFCC99"),c("#CC9999","#CCCC99"), c("#0099CC","#FF6666"),c("#339966","#996699

Is there a way to efficiently change hue of a 2D OpenGL texture using GLSL (fragment shader)? Do someone have some code for it? UPDATE: This is the code resulting from user1118321 suggestion: uniform sampler2DRect texture; const mat3 rgb2yiq = mat3(0.299, 0.587, 0.114, 0.595716, -0.274453, -0.321263, 0.211456, -0.522591, 0.311135); const mat3 yiq2rgb = mat3(1.0, 0.9563, 0.6210, 1.0, -0.2721, -0.6474, 1.0, -1.1070, 1.7046); uniform float hue; void main() { vec3 yColor = rgb2yiq * texture2DRect(texture, gl_TexCoord[0].st).rgb; float originalHue = atan(yColor.b, yColor.g); float finalHue =

问题 I am using the Hue filter to change the hue of an image: CIFilter* hueFilter = [CIFilter filterWithName:@"CIHueAdjust" <blah blah> [NSNumber numberWithFloat:hue], nil]; I have the Hue number I wish to use from Photoshop , but it doesn't correspond to the results I get from iOS. Is there a rule to change the number in PhotoShop to the number I should use in iOS ? 回答1: The Hue in HSL/HSV color mode is an angular coordinate. In Photoshop, it is given in degrees (-180 to +180). In the CIHueAdjust

How to programmatically change the hue of UIImage?

牧云@^-^@ 提交于 2019-11-27 06:42:18
I am very new to the image processing. I have to implement hue effect in my iPhone application project. Therefore, I need to change the hue of UIImage . Please provide me any sample code or tutorial link for this. Thanks in advance First, you need to decide if you are making an image a fixed hue , or rotating the existing hue . Examples of both are shown below. Fixed hue Fixing the hue can be done using the standard drawing tools - just make sure the blend mode is set to kCGBlendModeHue , and draw with the appropriate hue. This is derived from Nitish's solution, although I found that making
