按Bucket配置OSS/OSS-HDFS Credential Provider - E-MapReduce

本文為您介紹如何按Bucket配置OSS/OSS-HDFS Credential Provider。

按照Bucket配置Credential Provider

<configuration>
    <property>
        <name>fs.oss.bucket.XXX.credentials.provider</name>
        <value>com.aliyun.jindodata.oss.auth.SimpleAliyunCredentialsProvider,com.aliyun.jindodata.oss.auth.EnvironmentVariableCredentialsProvider,com.aliyun.jindodata.oss.auth.CommonCredentialsProvider</value>
        <description>配置com.aliyun.jindodata.oss.auth.AliyunCredentialsProvider的實作類別，多個類時使用英文逗號（,）隔開，按照先後順序讀取Credential直至讀到有效Credential。Provider詳情請參見Credential Provider類型。</description>
    </property>
</configuration>

說明

XXX為OSS/OSS-HDFS Bucket名稱。

Credential Provider類型

您可以根據情況，選擇不同的Credential Provider，支援如下Credential Provider類型：

Credential Provider類型	說明
TemporaryCredentialsProvider	適合使用有時效性的AccessKey和SecurityToken訪問OSS或OSS-HDFS的情況。
SimpleCredentialsProvider	適合使用長期有效AccessKey訪問OSS或OSS-HDFS的情況。
EnvironmentVariableCredentialsProvider	在環境變數中擷取AccessKey。
CommonCredentialsProvider	通用配置。

TemporaryCredentialsProvider

配置Provider類型

<configuration>
    <property>
        <name>fs.oss.bucket.XXX.credentials.provider</name>
        <value>com.aliyun.jindodata.oss.auth.TemporaryCredentialsProvider</value>
    </property>
</configuration>

配置OSS或OSS-HDFS AccessKey

<configuration>
    <property>
        <name>fs.oss.bucket.XXX.accessKeyId</name>
        <value>OSS/OSS-HDFS bucket的AccessKey Id</value>
    </property>
    <property>
        <name>fs.oss.bucket.XXX.accessKeySecret</name>
        <value>OSS/OSS-HDFS bucket的AccessKey Secret</value>
    </property>
    <property>
        <name>fs.oss.bucket.XXX.securityToken</name>
        <value>OSS/OSS-HDFS bucket的SecurityToken（臨時安全性權杖)</value>
    </property>
</configuration>

SimpleCredentialsProvider

配置Provider類型

<configuration>
    <property>
        <name>fs.oss.bucket.XXX.credentials.provider</name>
        <value>com.aliyun.jindodata.oss.auth.SimpleCredentialsProvider</value>
    </property>
</configuration>

配置OSS或OSS-HDFS AccessKey

<configuration>
    <property>
        <name>fs.oss.bucket.XXX.accessKeyId</name>
        <value>OSS/OSS-HDFS bucket的AccessKey Id</value>
    </property>
    <property>
        <name>fs.oss.bucket.XXX.accessKeySecret</name>
        <value>OSS/OSS-HDFS bucket的AccessKey Secret</value>
    </property>
</configuration>

EnvironmentVariableCredentialsProvider

配置Provider類型

<configuration>
    <property>
        <name>fs.oss.bucket.XXX.credentials.provider</name>
        <value>com.aliyun.jindodata.oss.auth.EnvironmentVariableCredentialsProvider</value>
    </property>
</configuration>

配置OSS或OSS-HDFS AccessKey

需要在環境變數中配置以下參數：

參數	說明
OSS_ACCESS_KEY_ID	OSS或OSS-HDFS的AccessKey ID。
OSS_ACCESS_KEY_SECRET	OSS或OSS-HDFS的AccessKey Secret。
OSS_SECURITY_TOKEN	OSS或OSS-HDFS的SecurityToken（臨時安全性權杖）。說明僅配置有時效Token時需要。

CommonCredentialsProvider

配置Provider類型

<configuration>
    <property>
        <name>fs.oss.bucket.XXX.credentials.provider</name>
        <value>com.aliyun.jindodata.oss.auth.CommonCredentialsProvider</value>
    </property>
</configuration>

配置OSS或OSS-HDFS AccessKey

<configuration>
    <property>
        <name>jindo.common.accessKeyId</name>
        <value>OSS/OSS-HDFS Bucket的AccessKey Id</value>
    </property>
    <property>
        <name>jindo.common.accessKeySecret</name>
        <value>OSS/OSS-HDFS Bucket的AccessKey Secret</value>
    </property>
    <property>
        <name>jindo.common.securityToken</name>
        <value>OSS/OSS-HDFS Bucket的SecurityToken（臨時安全性權杖)。僅配置有時效Token時需要。</value>
    </property>
</configuration>
