Description

I create tomcat app on my cluster using user yarn.but when starting tomcat component, throws Exception when copy application.resources to install webapps.

Traceback (most recent call last):

belows is the sources file and dst file
[root@sgserver004 resources]# ll slider-test.war
lrwxrwxrwx 1 yarn hadoop 102 May 12 19:27 slider-test.war -> /hadoop/yarn/local/usercache/fys/appcache/application_1463037266860_0007/filecache/113/slider-test.war

dst file:
[root@sgserver004 webapps]# ll slider-test.war
-r-x------ 1 yarn hadoop 0 May 12 19:27 slider-test.war

I think errors is that , shutil.copy(src,dist) with src file with permission rwxrwxrwx,but dst file is -r-x------, but why?
by the way , user yarn and root's umask is 0022
