> ViewFS should initialize target filesystems lazily
> --------------------------------------------------
>
> Key: HADOOP-17028
> URL: https://issues.apache.org/jira/browse/HADOOP-17028
> Project: Hadoop Common
> Issue Type: Bug
> Components: client-mounts, fs, viewfs
> Affects Versions: 3.2.1
> Reporter: Uma Maheswara Rao G
> Assignee: Abhishek Das
> Priority: Major
> Labels: pull-request-available
> Time Spent: 20m
> Remaining Estimate: 0h
>
> Currently viewFS initialize all configured target filesystems when
> viewfs#init itself.
> Some target file system initialization involve creating heavy objects and
> proxy connections. Ex: DistributedFileSystem#initialize will create DFSClient
> object which will create proxy connections to NN etc.
> For example: if ViewFS configured with 10 target fs with hdfs uri and 2
> targets with s3a.
> If one of the client only work with s3a target, But ViewFS will initialize
> all targets irrespective of what clients interested to work with. That means,
> here client will create 10 DFS initializations and 2 s3a initializations. Its
> unnecessary to have DFS initialization here. So, it will be a good idea to
> initialize the target fs only when first time usage call come to particular
> target fs scheme.
