Subject [jira] [Commented] (BEAM-2500) Add support for S3 as a Apache Beam FileSystem
Date Wed, 20 Sep 2017 16:00:16 GMT

    [ https://issues.apache.org/jira/browse/BEAM-2500?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16173403#comment-16173403
] 

Jacob Marble commented on BEAM-2500:
------------------------------------

I see this warning thousands of times when reading from S3:

Sep 20, 2017 8:45:04 AM com.amazonaws.services.s3.internal.S3AbortableInputStream close
WARNING: Not all bytes were read from the S3ObjectInputStream, aborting HTTP connection. This
is likely an error and may result in sub-optimal behavior. Request only the bytes you need
via a ranged GET or drain the input stream after use.

It looks like TextIO requests bytes n through m, but only consumes less than m-n bytes, then
closes the channel (channel wraps a stream). Am I wrong? Is m-n predictably small enough that
I should drain the stream at close?

> Note that this is for providing direct integration with S3 as an Apache Beam FileSystem.
> There is already support for using the Hadoop S3 connector by depending on the Hadoop
File System module[1], configuring HadoopFileSystemOptions[2] with a S3 configuration[3].
