提取命令：EXPORT table hx_dws.dws_fin_stock_hsgt_minute_trans TO “hdfs://hadoopNA/tmp/test/line_” PROPERTIES ( “column_separator”=",", “line_delimiter”="\n", “load_mem_limit”=“2147483648”, “timeout” = “3600” ) WITH BROKER “broker1” ( “username” = “hdfs”, “password” = “”);
hx_dws.dws_fin_stock_hsgt_minute_trans为逻辑视图表，
提取视图表时报错：Db does not exist. name: hx_dws，如果切换为物理表时则没有问题。
