Description

From customer case:

We are trying upgrade Ambari from 2.2.2 to Ambari 2.4 with the latest packages (1226).

https://issues.apache.org/jira/browse/AMBARI-15947 - "Upgrading Ambari should delete any pyc files"

The patch contains the following two lines

AMBARI_SERVER="${ROOT}/usr/lib/python2.6/site-packages/ambari_server"
find $AMBARI_SEVER/ -name *.pyc -exec rm {} \;

The AMBARI_SEVER typo basically executes "find / -name *.pyc -exec rm {} \;"
on the root directory and deletes ALL pyc files from the ambari server machine.

This looks like a bug in the latest Ambari package we released yesterday.

Considering the command has both "rm" and "*" in the same line, lets see if we can use a safer strategy such as changing the CWD and then deleting files.
