Just checking if there’s any update on the plan to merge this. Wondering if it's likely to land soon or if there's anything still under discussion. Appreciate any insights

> Currently, DFSClients send lease renewals to the NameNode at an interval equal to half of {{ipc.client.rpc-timeout.ms}}. This logic dates back to 2009 in HDFS-278. At my company, we are interested in using short DFS client timeouts (< 10 seconds). However, we're currently hesitant to do so because that would flood the NameNode with lease renewals.
> I propose a setting {{dfs.client.lease.renewal.interval.ms}} that, if nonzero, would be used as the lease renewal interval instead of {{ipc.client.rpc-timeout.ms / 2}}. This would be useful for advanced users that want to control their RPC timeout and lease renewals separately.
