Summary: Improvements for Hadoop read from AliyunOSS
Key: HADOOP-15027
URL: https://issues.apache.org/jira/browse/HADOOP-15027
Project: Hadoop Common
Issue Type: Improvement
Components: fs/oss
Reporter: wujinhu
Currently, read performance is poor when Hadoop reads from AliyunOSS. It needs
about 1min to read 1GB from OSS.
Class AliyunOSSInputStream uses single thread to read data from AliyunOSS, so
we can refactor this by using multi-thread pre read to improve this.
