(was: Thanks [~vanzin] for pointing out the jira, looks like most part of the ideas are similar. I'm not sure what is your progress on it, I think it would be great to collaborate to make that happen. Thanks a lot. )
> Add a new Configurable Token Manager for Spark Running on YARN
> ---------------------------------------------------------------
>
> Key: SPARK-16342
> URL: https://issues.apache.org/jira/browse/SPARK-16342
> Project: Spark
> Issue Type: New Feature
> Components: YARN
> Reporter: Saisai Shao

> Current Spark on YARN token management has some problems:
> 1. Supported service is hard-coded, only HDFS, Hive and HBase are supported for token fetching. For other third-party services which need to be communicated with Spark in Kerberos way, currently the only way is to modify Spark code.
> 2. Current token renewal and update mechanism is also hard-coded, which means other third-party services cannot be benefited from this system and will be failed when token is expired.
> 3. Also In the code level, current token obtain and update codes are placed in several different places without elegant structured, which makes it hard to maintain and extend.
> So here propose a new Configurable Token Manager class to solve the issues mentioned above.
> Basically this new proposal will have two changes:
> 1. Abstract a ServiceTokenProvider for different services, this is configurable and pluggable, by default there will be hdfs, hbase, hive service, also user could add their own services through configuration. This interface offers a way to retrieve the tokens and token renewal interval.
> 2. Provide a ConfigurableTokenManager to manage all the added-in token providers, also expose APIs for external modules to get and update tokens.
> Details are in the design doc (https://docs.google.com/document/d/1piUvrQywWXiSwyZM9alN6ilrdlX9ohlNOuP4_Q3A6dc/edit?usp=sharing), any suggestion and comment is greatly appreciated.
