使用 python 將文件從 azure 數據湖 Gen 1 移動到臨時目錄

Question

如何使用 python 將文件從 azure 數據湖 Gen 1 移動到臨時目錄？ 我需要在 ADL 中找到每個文件，將其移動到臨時目錄以解密並讀取它。

我在用

azure.datalake.store import core
core.AzureDLFileSystem(token, 'store_name')

#create a temp directory
 with tempfile.TemporaryDirectory() as tmpdirname:

關於這個問題，請參考以下代碼

from azure.datalake.store import core, lib, multithreaded

##auth
adlCreds = lib.auth(tenant_id = tenant,
                client_secret = client_secret,
                client_id = client_id,
                resource = RESOURCE)
subscriptionId = 'FILL-IN-HERE'
adlsAccountName = 'FILL-IN-HERE'

## Create a filesystem client object
adlsFileSystemClient = core.AzureDLFileSystem(adlCreds, store_name=adlsAccountName)


## Download a file
multithread.ADLDownloader(adlsFileSystemClient, lpath='<local path>', rpath='<path on adls>', nthreads=64, overwrite=True, chunksize=4194304,buffersize=4194304, blocksize=4194304)

##Move file between locations on ADL
adlsFileSystemClient.mv('<Source Path>','Destination path')
