Hanisha Koneru updated HDDS-4068:
---------------------------------
Summary: Client should not retry same OM on network connection failure
(was: Client Retry for ipc.client.connect.max.retries when first OM is down)
> Client should not retry same OM on network connection failure
> -------------------------------------------------------------
>
> Key: HDDS-4068
> URL: https://issues.apache.org/jira/browse/HDDS-4068
> Project: Hadoop Distributed Data Store
> Issue Type: Bug
> Components: OM HA, Ozone Client
> Reporter: Bharat Viswanadham
> Assignee: Hanisha Koneru
> Priority: Major
>
> Right now retry logic on client to OM is, it will try connect to OM1, if it
> is leader fine, else try with next OM and so on. If OM1, is down, client
> retries for 50 times when ipc.client.connect.max.retries is set to 50 and
> ipc.client.connect.retry.interval default to 1sec, so a total of 50seconds is
> spent in retry and then move to next OM.
> I think here client -> OM should have its own retry policy, in this way if
> the first OM is down, to complete request, the user does not need to wait for
> 50sec.
> As ipc.client.connect.retry.interval and ipc.client.connect.max.retries are
> common configurations for RPC, creating a new default retry policy with
> smaller values would be nice.
