]

Suresh Srinivas resolved HDFS-4343.
-----------------------------------

    Resolution: Invalid

Closing this jira as Invalid. The behavior in the description is the expected behavior. When
storage directories are in inconsistent state, invalid or stale directories are expected to
be cleaned manually, before restarting a datanode.

If you disagree, feel free to reopen the jira. Please justify why you think it is a valid
jira, when you reopen the jira.

> A datanode has multiple storage directories configured using dfs.data.dir. When the storageID
in the VERSION files in these directories, the datanode fails to startup. Consider a scenario,
when old data in a storage directory is not cleared, the storage ID from it will not match
with storage ID of in other storage storage directories. In this situation, the DataNode will
quit and restart fails.
