This patch adds support for OSS (Aliyun Object Storage Service). Using the hadoop-aliyun, the implementation is similar to other remote FileSystems. Tests: - Prepare: Initialize OSS-related environment variables: OSS_ACCESS_KEY_ID, OSS_SECRET_ACCESS_KEY, OSS_ACCESS_ENDPOINT. Compile and create hdfs test data on a ECS instance. Upload test data to an OSS bucket. - Modify all locations in HMS DB to point to the OSS bucket. Remove some hdfs caching params. Run CORE tests.
