> Remove HDFS Binaries/Jars Dependency From YARN
> ----------------------------------------------
>
>                 Key: YARN-11664
>                 URL: https://issues.apache.org/jira/browse/YARN-11664
>             Project: Hadoop YARN
>          Issue Type: Improvement
>          Components: yarn
>            Reporter: Syed Shameerur Rahman
>            Priority: Major
>              Labels: pull-request-available
>
> In principle Hadoop Yarn is independent of HDFS. It can work with any 
> filesystem. Currently there exists some code dependency for Yarn with HDFS. 
> This dependency requires Yarn to bring in some of the HDFS binaries/jars to 
> its class path. The idea behind this jira is to remove this dependency so 
> that Yarn can run without HDFS binaries/jars
> *Scope*
> 1. Non test classes are considered
> 2. Some test classes which comes as transitive dependency are considered
> *Out of scope*
> 1. All test classes in Yarn module is not considered
>  
> --------------------------------------------------------------------------------------------------------------------------------------------------------------------
> A quick search in Yarn module revealed following HDFS dependencies
> 1. Constants
> {code:java}
> import 
> org.apache.hadoop.hdfs.security.token.delegation.DelegationTokenIdentifier;
> import org.apache.hadoop.hdfs.DFSConfigKeys;{code}
>  
>  
> 2. Exception
> {code:java}
> import org.apache.hadoop.hdfs.protocol.DSQuotaExceededException;
>  
> 3. Utility
> {code:java}
> import org.apache.hadoop.hdfs.protocol.datatransfer.IOStreamPair;{code}
>  
> Both Yarn and HDFS depends on *hadoop-common* module,
> * Constants variables and Utility classes can be moved to *hadoop-common*
> * Instead of DSQuotaExceededException, Use the parent exception 
> ClusterStoragrCapacityExceeded
