---------------------------
Summary: Fix UpgradeDowngrade Rename Exception in aliyun OSS
Key: HUDI-1268
URL: https://issues.apache.org/jira/browse/HUDI-1268
Project: Apache Hudi
Issue Type: Bug
Components: Writer Core
Reporter: leesf
Fix For: 0.6.1
when using HoodieWriteClient API to write data to hudi with following config:
```
Properties properties = new Properties();
properties.setProperty(HoodieTableConfig.HOODIE_TABLE_NAME_PROP_NAME,
tableName);
properties.setProperty(HoodieTableConfig.HOODIE_TABLE_TYPE_PROP_NAME,
tableType.name());
properties.setProperty(HoodieTableConfig.HOODIE_PAYLOAD_CLASS_PROP_NAME,
OverwriteWithLatestAvroPayload.class.getName());
properties.setProperty(HoodieTableConfig.HOODIE_ARCHIVELOG_FOLDER_PROP_NAME,
"archived");
return HoodieTableMetaClient.initTableAndGetMetaClient(hadoopConf, basePath,
properties);
```
the exception will be thrown with FileAlreadyExistsException in aliyun OSS,
after debugging, it is the following code throws the exception.
```
// Rename the .updated file to hoodie.properties. This is atomic in hdfs, but
not in cloud stores.
// But as long as this does not leave a partial hoodie.properties file, we are
okay.
fs.rename(updatedPropsFilePath, propsFilePath);
```
however, we would ignore the FileAlreadyExistsException since hoodie.properties
already exists.
