This is Sebastian-level grammar. Please upgrade to Brian-level grammar.

This boolean does more than just check whether a smaller batch should be used. It also checks the size of the current batch. I think we need to move some logic or change the name.

| if (op.getBackoffDuration() > 0) { |

I am a bit confused. Why do we need this and retryInSmallerBatch? Is it possible to remove one of these checks?

The first check involving retryInSmallerBatch ensures that we are adding the retry to an appropriate batch. For example, if the batch already had 15 writes enqueued, and sendOperationLocked() is called with a retry, BulkWriter needs to first send the existing batch to create a new batch of size 10.
Consolidated the checks into a single if statement at the start of the function.
| bulkCommitBatch.setMaxBatchSize(RETRY_MAX_BATCH_SIZE); | ||
| } | ||

| if (bulkCommitBatch.getMutationsSize() == bulkCommitBatch.getMaxBatchSize()) { |

... especially since we are reading the value right back here.
