NameNode和SecondaryNameNode工作机制 NameNode主要是存放一些元数据信息,那么这些元数据信息如果存放在磁盘中,每次请求都去磁盘中查找元数据,这样效率很慢,所以在Hadoop中元数据都是存放在内存中的。这样会带来一个问题,如果掉电,内存中的数据就没有了,所以为了保证元数据的安全性,所以需要对内存中的元数据进行备份。
目录1、偏移问题现象描述 2、偏移矫正过程 QGIS加载在线地图的方式有很多贴,本文就不再细说了。 方法贴 在线地图贴 1、偏移问题现象描述 批量导入WGS坐标点后发现和底图存在偏移情况 2、偏移矫正过程 下载安装geohey插件,将WGS坐标转换成火星坐标(GCJ02,高德、谷歌地图都是用的这个坐标),然后再显示就正确了。 插件...
Instead of a hardcoded keychain ID key, use a key which is unique per QGIS user profile so that we don't overwrite other profile's master passwords when using secondary profiles, avoiding an un-encryptable auth database in other profiles.PR at qgis/QGIS#55141...
