Tsz Wo (Nicholas), SZE updated HADOOP-3883:
-------------------------------------------
Attachment: 3883_20081007.patch
3883_20081007.patch:
- Limit namenode to assign at most one generation stamp for a particular block
within a short period, which is 10 seconds defined in
FSConstants.LEASE_RECOVER_PERIOD.
- Introduce GenerationStamp.UpdateException so that update from a higher gs to
a lower gs will be stopped.
- Introduce BlockRecoveryException. This is another bug: Previously, null is
returned in DataNode.syncBlock(...) for both normal case and error case.
