Genmao Yu updated HADOOP-15038:
-------------------------------
Description:
Open this JIRA to discuss if we should move {{MetadataStore}} in {{S3Guard}}
into a common module.
Based on this work, other filesystem or object store can implement their own
metastore for optimization (known issues like consistency problem and metadata
operation performance). [[email protected]] and other guys have done many base
and great works in {{S3Guard}}. It is very helpful to start work. 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.
