Review Comment:
   We can remove this as it will not likely be executed for successful test 
scenario.

Review Comment:
   As per this comment, we will likely not hit the case where 
`totalfailedMutation < numFailedMutations`?

>             Project: Phoenix
>          Issue Type: Bug
>    Affects Versions: 4.15.0
>            Reporter: Chinmay Kulkarni
>            Assignee: Aman Poonia
>            Priority: Major
>              Labels: metrics, phoenix-hardening, quality-improvement
>             Fix For: 4.17.0, 4.16.2
>
>
> In the conn.commit() path, we get the number of mutations that failed to be 
> committed in the catch block of MutationState.sendMutations() (see 
> [here|https://github.com/apache/phoenix/blob/dcc88af8acc2ba8df10d2e9d498ab3646fdf0a78/phoenix-core/src/main/java/org/apache/phoenix/execute/MutationState.java#L1195-L1198]).
>  
> In case of delete mutations, the uncommittedStatementIndexes.length always 
> resolves to 1 and we always update the metric value by 1 in this case, even 
> though the actual mutation list corresponds to multiple DELETE mutations 
> which failed. In case of upserts, using unCommittedStatementIndexes.length is 
> fine since each upsert query corresponds to 1 Put. We should fix the logic 
> for deletes/mixed delete + upsert mutation batch failures.
> This wrong value is propagated to global client metrics as well as 
> MutationMetricQueue metrics.
