…ss to OSS-HDFS (#42585) Fix the problem that paimon catalog can not access to OSS-HDFS. There are 2 problems in paimon catalog: 1. Doris FE can not list paimon tables. This is because we pass these three properties -- `fs.oss.endpoint / fs.oss.accessKeyId / fs.oss.accessKeySecret` -- to the PaimonCatalog. When PaimonCatalog get these three properties, it will use `OSSLoader` rather than `HadoopFileIOLoader`. 2. Doris BE does not use libhdfs to access OSS-HDFS This is because the `tmpLocation` in `LocationPath` does not contain `oss-dls.aliyuncs`. We should use `endpoint` to judge if user wants to access OSS-HDFS What's more, if you want to access OSS-HDFS with PaimonCatalog, you should: 1. Download Jindo SDK: https://github.com/aliyun/alibabacloud-jindodata/blob/latest/docs/user/zh/jindosdk/jindosdk_download.md 2. copy `jindo-core.jar、jindo-sdk.jar` to `${DORIS_HOME}/fe/lib` and `${DORIS_HOME}/be/lib/java_extensions/preload-extensions` directory.

Fix the problem that paimon catalog can not access to OSS-HDFS.
There are 2 problems in paimon catalog:
Doris FE can not list paimon tables.
This is because we pass these three properties --
fs.oss.endpoint / fs.oss.accessKeyId / fs.oss.accessKeySecret-- to the PaimonCatalog. When PaimonCatalog get these three properties, it will useOSSLoaderrather thanHadoopFileIOLoader.Doris BE does not use libhdfs to access OSS-HDFS
This is because the
tmpLocationinLocationPathdoes not containoss-dls.aliyuncs. We should useendpointto judge if user wants to access OSS-HDFSWhat's more, if you want to access OSS-HDFS with PaimonCatalog, you should:
