When becoming active, NN should treat all leases as freshly renewed
-------------------------------------------------------------------
Key: HDFS-2812
URL: https://issues.apache.org/jira/browse/HDFS-2812
Project: Hadoop HDFS
Issue Type: Sub-task
Components: ha, name-node
Affects Versions: HA branch (HDFS-1623)
Reporter: Todd Lipcon
Assignee: Todd Lipcon
Priority: Critical
I haven't seen this yet in practice, but I think the following is a bug:
- Clients currently only renew leases to the active NN
- Leases are written into the log when created, but there is no record to renew
them
- In Standby state, we don't check leases for expiration. But, when we fail
over and start the lease monitor, since the leases haven't been renewed, they
might end up getting incorrectly released.
