Chris Nauroth commented on HADOOP-13728: ---------------------------------------- || Alias || Class || | anonymous | org.apache.hadoop.fs.s3a.AnonymousAWSCredentialsProvider | | env | com.amazonaws.auth.EnvironmentVariableCredentialsProvider | | instance-profile | org.apache.hadoop.fs.s3a.SharedInstanceProfileCredentialsProvider | | simple | org.apache.hadoop.fs.s3a.SimpleAWSCredentialsProvider | | temporary | org.apache.hadoop.fs.s3a.TemporaryAWSCredentialsProvider | Therefore, the typical default provider chain could be expressed as: {code} <property> <name>fs.s3a.aws.credentials.provider</name> <value>simple,env,instance-profile</value> </property> {code} For any configuration value not listed as an alias above, assume it's a full class name, and fall back to the current logic. This also means the change would be fully backward-compatible with existing configuration files that already use the full class names, or highly customized deployments that used their own subclass implementations of {{AWSCredentialsProvider}}. > S3A can support short user-friendly aliases for configuration of credential > providers. > -------------------------------------------------------------------------------------- > > Key: HADOOP-13728 > URL: https://issues.apache.org/jira/browse/HADOOP-13728 > Project: Hadoop Common > Issue Type: Sub-task > Components: fs/s3 > Reporter: Chris Nauroth > Priority: Minor > > This issue proposes to support configuration of the S3A credential provider > chain using short aliases to refer to the common credential providers in > addition to allowing full class names. Supporting short aliases would > provide a simpler operations experience for the most common cases. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
