> Store INodeId instead of the INodeFile object in BlockInfoContiguous

> Key: HDFS-8248
> URL: https://issues.apache.org/jira/browse/HDFS-8248
> Project: Hadoop HDFS

>
> Currently the namespace and the block manager are tightly coupled together.
> There are two couplings in terms of implementation:
> 1. The {{BlockInfoContiguous}} stores a reference of the {{INodeFile}} that
> owns the block, so that the block manager can look up the corresponding file
> when replicating blocks, recovering from pipeline failures, etc.
> 1. The {{INodeFile}} stores {{BlockInfoContiguous}} objects that the file
> owns.
> Decoupling the namespace and the block manager allows the BM to be separated
> out from the Java heap or even as a standalone process. This jira proposes to
> remove the first coupling by storing the id of the inode instead of the
> object reference of {{INodeFile}} in the {{BlockInfoContiguous}} class.
