ptlrs opened a new pull request, #10482:
URL: https://github.com/apache/ozone/pull/10482
## What changes were proposed in this pull request?
Some of the configuration values for the ratis client are too long such that
they make the client appear non-responsive.
This jira updates some of the configurations to make the client be more
responsive to failures on the server side
- Exponential Backoff (for TimeoutIOException on writes):
- Base sleep: 4s to 1s — faster initial retry
- Max sleep cap: 40s to 5s — don't wait long between retries on a dead
leader
- Max retries: unlimited (Integer.MAX_VALUE) to 2 — if 2 retries fail, the
leader is dead. We will let Ozone allocate a new pipeline
- Multilinear Random Retry (for generic/other exceptions):
- Policy: 5s×5, 10s×5, 15s×5, 20s×5, 25s×5, 60s×10 (~16 min, 35 retries)
to 5s×6 (~30s total) — fail fast instead of hanging
- Watch Timeout (waiting for ALL_COMMITTED replication):
- Overall watch timeout: 3 min to 30s
- Watch RPC timeout: 180s to 30s — aligned with server-side watch timeout
(also 30s). There's no point waiting longer than the server
- Write Timeout (overall budget for write retries):
- Write request timeout: 5 min to 70s — enough for one RPC (60s) + buffer.
This prevents retries from dragging on
