> Correctly reconstruct erasure coding file from FSImage

>             Project: Hadoop HDFS
>          Issue Type: Bug
>          Components: erasure-coding
>    Affects Versions: 3.0.0-alpha1
>            Reporter: SammiChen
>            Assignee: SammiChen
>            Priority: Critical
>              Labels: hdfs-ec-3.0-must-do

>
> Currently, FSImageFormatProtoBuf has the information about whether the file 
> is striped or not and saved file's erasure coding policy ID in replication 
> field. But later, when FSImage is loaded to create the name space, the 
> default system erasure coding policy is used to reconstruct file's block 
> structure.  In case if the erasure coding policy of file is not the default 
> erasure coding policy, the content of the file cannot be accessed correctly.
