Steve Loughran commented on HADOOP-17372: ----------------------------------------- Thinking about this proposed (here and in ABFS) in initialize(), the cloned Configuration SHALL have its classloader set to this.getClass.getCloassloader so that all classes loaded in it are visible/consistent with the FS > S3A AWS Credential provider loading gets confused with isolated classloaders > ---------------------------------------------------------------------------- > > Key: HADOOP-17372 > URL: https://issues.apache.org/jira/browse/HADOOP-17372 > Project: Hadoop Common > Issue Type: Sub-task > Components: fs/s3 > Affects Versions: 3.4.0 > Reporter: Steve Loughran > Priority: Major > > Problem: exception in loading S3A credentials for an FS, "Class class > com.amazonaws.auth.EnvironmentVariableCredentialsProvider does not implement > AWSCredentialsProvider" > Location: S3A + Spark dataframes test > Hypothesised cause: > Configuration.getClasses() uses the context classloader, and with the spark > isolated CL that's different from the one the s3a FS uses, so it can't load > AWS credential providers. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
