Mingliang Liu commented on HADOOP-13959:
----------------------------------------
+1 for the proposal.
Thanks [~ste...@apache.org] for filing this! This is definitely something we
have to do for scaling the S3Guard much better. According to our effort in
[HADOOP-13908], we may have to test this patch carefully especially when
waiting a newly created table for active. [AWS

discussion thread.
> S3guard: replace dynamo.describe() call in init with more efficient query

> Affects Versions: HADOOP-13345
> Reporter: Steve Loughran
> Priority: Minor

> HADOOP-13908 adds initialization when a table isn't created, using the
> {{describe()}} call.
> AWS document this as inefficient, and throttle it. We should be able to get
> away with a simple table lookup as the probe
