imay opened a new issue #2001: Use Env to do file operation
URL: https://github.com/apache/incubator-doris/issues/2001
 
 
   Now, in many place, we use posix interface or boost function to do file operation. We have abstract an Env interface to do file operation. 
   We should change it to use Env to do file operation for following reason.
   1. we can unify all file operation in one place, it is easy for us to do some work later, for example audit.
   2. we can use one copy of code to do the same things to avoid duplicated code.
   3. If we want to our code to access remote file, we will do it without logical code modify.
   
   There are too many places to be changed, so this work will be split into some smaller job to finish.
