-----------------------------------------------------------------
Looks good [~mnpoonia]! I am not 100% sure but it seems that PHOENIX-6420 and
PHOENIX-6397 have resolved this issue if it was present before, and we should
definitely have this test present to ensure this metrics is correctly updated
for multiple Delete mutations.

> 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.
