mongoimport doesn`t support retryWrites=false when importing data to shard cluster

Hi, 

having env with shard cluster on local SERVER:55555, version 4.4.1.

Following import command:

echo fff | mongoimport mongodb://czcholsint1611:55555/C360?retryWrites=false -c test --type=tsv -f 1 --version

return err:

Failed: this MongoDB deployment does not support retryable writes. Please add retryWrites=false to your connection string

when I try same command against Standalone mongod SERVER:33331 (4.4.1) I get no err:

echo fff | mongoimport mongodb://SERVER:33331/C360?retryWrites=false -c test --type=tsv -f 1

connected to: mongodb://czcholsint1611:33331/C360?retryWrites=false
1 document(s) imported successfully. 0 document(s) failed to import.

best regards

marian
