wujinhu updated HADOOP-15027:
-----------------------------
Description: Currently, AliyunOSSInputStream uses single thread to read
data from AliyunOSS, so we can refactor this by using multi-thread pre-read to
improve read performance. (was: 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.)
