利用Arcgis提取nc数据并计算区域年均温 1.下载数据。2.解压数据至不含中文的路径中。打开工具箱中的多维分析工具-创建NetCDF栅格图层，导入数据。3.打开工具箱中的数据管理工具-图层和表视图-创建栅格图层，导入数据，对输出数据进行命名，得到月均温栅格数据。4.选择工具箱-Spatial Analyst工具（空间分析工具）-地图代数-栅格计算器，计算全国一年年均温。5.将其导出为.tif格式数据，方便后期使用。6.选择工具箱-Spatial Analyst工具（空间分析工具）-区域分析--以表格显示分区统计，得到分区域的气温数据。阅读详情

master(standby)

slave1(active)

slave2

zookeeper节点:
[zookeeper, yarn-leader-election, hadoop-ha, hbase]

在HA环境下启动HBase, 我根据日志分析slave2上regionserver获取namenode连接到了standby的机器上，貌似不能识别active和standby，很是奇怪请大神指导。。。
