Install Hue without Cloudera

这一生的挚爱 提交于 2019-12-09 14:25:34
问题 Has anyone tried/succeeded in installing Hue on Hadoop without Cloudera? I have gotten to a point where I can reliably reproduce a hadoop cluster with hbase and hive and can set it all up in about 15 minutes. I'd love to have Hue along with all this without having to go back and redo my setup with Cloudera. 回答1: Checkout slides #19 & #5, Hue is getting everywhere and is compatible with Hadoop 0.20 / 1.2.0 / 2.2.0: http://gethue.com/hue-goes-to-paris-hug-france/ Hue has tarball releases

pytorch加速加载方案

pytorch没有像mxnet的RecordIO文件,每次读大量小图很是吃力,硬盘不给力的话耗时基本堵在加载数据上了,试过lmdb,快则快矣,然不支持训练过程中随机shuffle,终放弃。 盖天下苦其久矣,早有各路神仙献策, 此地 有个简单汇总,遂拾人牙慧,总结如下: 1. dali - 当前最靠谱方案,连数据增广也提供了 参考链接 pip install 安装,根据 手册 写几行代码就可以了,跟pytorch自带的dataloader用法基本一样,支持 数据增广 ,常用的都有了,需要搜索函数名看好具体用法,需要用dali自带的Uniform和CoinFlip做随机,如果用python自带random生成随机数,然后if _rand == 1的话只能生成一次,也就是说如果random生成了1那对于本次训练所有数据都做增广,而生成0就都不进行增广,这地方调了一个晚上,最后好好看手册里说明和git issue修改如下,感觉随机性可以了。 class reader_pipeline(Pipeline): def __init__(self, image_dir, batch_size, num_threads, device_id): super(reader_pipeline, self).__init__(batch_size, num_threads, device_id)

Hue/Hive user root is not allowed to impersonate Hue

Situation: I have set up Hive, Hue and Hadoop in different Docker Containers. In the same Docker network. I created a Container for each 1 Hadoop Namenode, 2 Datanodes,1 Hue instance, 1 Hive Server and a Postgres Metastore. I was able to configure a hue proxy user in the hdfs-site.xml of the namenode and can browse the filesystem via webhdfs. For Hive however I get the error within Hue: Failed to open new session: java.lang.RuntimeException: org.apache.hadoop.ipc.RemoteException (org.apache.hadoop.security.authorize.AuthorizationException): User: root is not allowed to impersonate hue I am

Faster method of changing an image hue?

↘锁芯ラ 提交于 2019-12-07 14:21:33
问题 Is there a better method to change the hue of an image smoothly as I slide through a trackbar? What I'm doing is getting the RGB value per pixel, calculating the saturation and brightness then putting the values in. The size of the image affects the speed the hue is updated. Photoshop's image hue function changes the hue from 0 to 360 smoothly which is what I want to try and get to. data = editImage.LockBits(new Rectangle(0, 0, editWidth, editHeight), ImageLockMode.ReadWrite, PixelFormat
