2.将文件file1转码,转后文件输出到fil2
模板：iconv -f SrcEncoding -t DestEncoding InputFile -o OutputFile
iconv -f gb2312 -t UTF- file1 -o file2 //没-o那么会输出到标准输出.
模板：iconv -f SrcEncoding -t DestEncoding InputFile -c -o OutputFile
3.从hive中取出的数据是utf8的，要load到mysql中，gbk编码。所以在load之前要先对文件进行转码
mysql_cmd = "iconv -c -f utf-8 -t gbk ./data/al_ver_" + yesterday_time + ".xls -o ./data/GBK_al_ver_" + yesterday_time + ".xls "
print(mysql_cmd)
os.system(mysql_cmd) mysql_cmd = "mysql -h60.28.200.78 -uroot -pyeelion -A LogStat_RT -e \"load data local infile \'./data/GBK_al_ver_" + yesterday_time + ".xls ' into table HiveData_508\""
print(mysql_cmd)
os.system(mysql_cmd)
