Subject [jira] [Updated] (HADOOP-15953) AliyunOSS: make AliyunCredentialsProvider compatible with the required constructor
Date Wed, 28 Nov 2018 01:34:00 GMT

     [ https://issues.apache.org/jira/browse/HADOOP-15953?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

wujinhu updated HADOOP-15953:
-----------------------------
    Description: 
Hadoop aliyun module uses AliyunCredentialsProvider as default CredentialsProvider if user
do not set fs.oss.credentials.provider. However, if user set fs.oss.credentials.provider
to org.apache.hadoop.fs.aliyun.oss.AliyunCredentialsProvider, exception will be thrown like
below:

 
{code:java}
java.io.IOException: org.apache.hadoop.fs.aliyun.oss.AliyunCredentialsProvider constructor
exception. A class specified in fs.oss.credentials.provider must provide an accessible constructor
accepting URI and Configuration, or an accessible default constructor.
