-------------------------------------------------
{quote} * Is this a genuine AWS S3 endpoint, or someone else's s3-compatible
one?{quote}
It is S3-compatible object store.
{quote}is there something "odd" about the files in your directory tree
{quote}
No, everythign is normal.
{quote} * if you install the aws sdk, does an {{aws s3 ls}} command work?{quote}
ls has same issue.
{quote} * Does this still happen on the Hadoop 3.2 release?{quote}
We didn't verified in 3.2. Our production cluster is 3.1.
{quote} * Is it only one specific bucket/path?{quote}
no, this is common for all the bucket.
*Currenlty we disbaled v2 and using v1.*
One thing I observed is *"<IsTruncated>true</IsTruncated>"* is always true in
response and call goes infinitely and it fetch same list again and again.
.Below is some http responce for list call
