MapReduce早已经对接了HBase,以HBase作为数据源,完成批量数据的读写。如今继MapReduce之后的Spark在大数据领域有着举足轻重的地位,无论跑批,流处理,甚至图计算等都有它的用武之地。Spark对接HBase成为不少用户的需求。 二.Spark On HBase 1.可以解决的问题 Spark和HBase无缝对接意味着我们不再需要关心安全和RDD与...

用python操作hbase时需要用到happybase库 python+happybase 1.pip install happybase 直接安装即可 2.测试安装 python -c ‘import happybase’,不报错就是正常的或直接导入happybase包不报错 3.安装thrift,thrift为一个语言编译器,在python去操作hbase是需要将语言重新编译为hbase底层支持的c++,具体可看https://www....

首先需要知道,图片转换成base64并不是加解密,而是编解码,主要的作用不在于安全性,而在于让内容能在各个网关间无错的传输,这才是Base64编码的核心作用。 1 base64编码原理 Base64编码是基于64个字符A-Z,a-z,0-9,+,/的编码方式,因为2的6次方正好为64,所以用6位就可以表示出这64个字符了。一个字节是8位,...
(often referred to as adata model) is implemented as a Python class and is used to map to a single database table. Once you’ve created your data models, you can use Django’s database-abstraction API to access and manipulate data in the mapped database tables in a pythonic way. This...
根据这个图我们得到关键信息:map数据直接给base_link,传感器或是轮子直接连接在base_link上,那么机器人主坐标系定了base_link,主坐标系我们会在后面的yaml文件里进行修改,而且这里我们得到我们并不需要amcl进行定位,因为是map直接发布的base_link,就很准不需...
