Использование Google Storage из Flink REPL

Я пытаюсь прочитать CSV-файл из облачного хранилища Google в Flink REPL. Поскольку я не очень разбираюсь во Flink, я предпочитаю работать в REPL, чтобы решать одну ошибку за раз, а не помещать свой код в JAR, а затем не знать, с чего начать со всеми ошибками.

В этом примере я буду использовать общедоступные данные Landsat в хранилище Google.

Я создал кластер dataproc и добавил сценарий bash, предоставленный облаком Google, для установки flink во время создания кластера. Скрипт можно найти здесь.

Поскольку я использую кластер dataproc, мне нужно только добавить банку gcs-connector в путь к классам. Итак, я запускаю Flink REPL следующим образом:

/usr/lib/flink/bin/start-scala-shell.sh yarn -a /usr/lib/hadoop/lib/gcs-connector-hadoop2-1.9.10.jar

Затем я импортирую облачное хранилище Google, используя эту строку кода в REPL:

 import com.google.cloud.hadoop.fs.gcs

Наконец, я пытаюсь прочитать общедоступный файл как текстовый и получаю следующую ошибку:

 val landsaturl = "gs://gcp-public-data-landsat/LC08/01/001/002/LC08_L1GT_001002_20160817_20170322_01_T2/LC08_L1GT_001002_20160817_20170322_01_T2_ANG.txt"
landsat.first(1).print()

Я пропустил шаг или это то, что невозможно сделать в REPL и можно сделать только с помощью толстой банки и указания вещей, связанных с облачным хранилищем Google, в pom.xml?
