Steve Loughran commented on FLINK-7589:
---------------------------------------
well, you are allowed to file bug reports.
However, it's not the s3 client getting GC'd, because the s3 client is retained
for the lifespan of the FileSystem instance, so unless you are disposing of
that, its retained.
I'd blame network connectivity: the connection was closed, you got back less
data than you asked for.
The s3a client does a single retry here, but it could be more sophisticated
(HADOOP-14531).
