I did some perf test in HADOOP-14098, and started related work for > Aliyun OSS. Indeed there are still works to do for {{S3Guard}}, like > metadata cache inconsistent with S3 and so on. It also will be a problem for > other object store. However, we can do these works in parallel. > [~ste...@apache.org] [~fabbri] [~drankye] Any suggestion is appreciated. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
