External issue URL: (was: https://github.com/apache/hbase/pull/6000)
> Client meta operation timeout does not default to the correct value
> -------------------------------------------------------------------
>
> Key: HBASE-28608
> URL: https://issues.apache.org/jira/browse/HBASE-28608
> Project: HBase
> Issue Type: Bug
> Components: Client
> Affects Versions: 2.6.0, 2.4.17, 3.0.0-beta-1, 2.5.8
> Reporter: Daniel Roudnitsky
> Assignee: Daniel Roudnitsky
> Priority: Major
> Labels: timeout

> Client meta operation timeout {{hbase.client.meta.operation.timeout}} default
> was intended to be set to the configured client operation timeout, but it
> defaults to the default client operation timeout of 20 minutes instead. This
> defeats the purpose of the meta operation timeout if one has a typical setup
> where {{hbase.client.operation.timeout}} << 20 minutes and
> {{hbase.client.meta.operation.timeout}} is not explicitly set, which can lead
> to operations taking much longer than the configured operation timeout to
> actually timeout if there is e.g meta slowness and/or contention around
> userRegionLock on 2.x. From "Timeout settings" in the hbase reference :
> {panel}
> A higher-level timeout is hbase.client.operation.timeout which is valid for
> each client call. When an RPC call fails for instance for a timeout due to
> hbase.rpc.timeout it will be retried until hbase.client.operation.timeout is
> reached. Client operation timeout for system tables can be fine tuned by
> setting hbase.client.meta.operation.timeout configuration value. When this is
> not set its value will use hbase.client.operation.timeout
> {panel}
