> For some sources and sinks, currently, passwords to keystores/other are 
> specified in clear text in the flume config file.   Since flume config files 
> are often easily accessible to a broader audience (like in source control for 
> instance), the visibility of these passwords can be too much and risky for 
> institutions where security is too critical (like banks) 
> To help address this visibility issue it would be desirable to do the 
> following two things :
> 1) Store the password in a separate file and provide the path of that 
> password file in the flume config. this will enable the flume config to be 
> shared with a wider audience and reduce risk. the password file will need to 
> be very tightly guarded. Some components like file channel & JMS source 
> already do this. 
> 2) As an additional measure, obfuscate the password in the external password 
> file. A simple command line tool can be used to generate the obfuscated 
> password file. Flume source/sink configuration will read the password file 
> and de-obfuscate the password before using it to access the keystore. This 
> obfuscation step IMO is nice but unclear to me if it is essential.
> The following Sources and Sinks appear to use inline cleartext passwords:
> - Avro Source
> - Avro sink
> - HTTP(S) source 
> - File Channel
> - JMS Source
> JDBC channel also uses inline passwords but i am not aware of anybody who 
> uses JDBC channel. So it may not be an issue.
