Federation: FSDataset in Datanode should be created after initial handshake
with namenode
-----------------------------------------------------------------------------------------
Key: HDFS-1637
URL: https://issues.apache.org/jira/browse/HDFS-1637
Project: Hadoop HDFS
Issue Type: Bug
Affects Versions: Federation Branch
Reporter: Jitendra Nath Pandey
Assignee: Jitendra Nath Pandey
Fix For: Federation Branch
Currently storage is initialized only after handshake with a namenode.However
FSDataset is created before handshake and hence before storage initialization.
At this time, storage does not have storage directories resulting in FSDataset
initialized with no volumes.
