> Implementing Timeout for HostFileReader when FS hangs
> -----------------------------------------------------
>
>                 Key: HDFS-17546
>                 URL: https://issues.apache.org/jira/browse/HDFS-17546
>             Project: Hadoop HDFS
>          Issue Type: Improvement
>          Components: namenode
>            Reporter: Simbarashe Dzinamarira
>            Assignee: Simbarashe Dzinamarira
>            Priority: Minor
>              Labels: pull-request-available
>
> Certain implementations of Hadoop have the dfs.hosts file residing on NAS/NFS 
> and potentially with symlinks. If the FS hangs for any reason, the 
> refreshNodes call would infinitely hang on the HostsFileReader until the FS 
> returns.
