Lei (Eddy) Xu commented on HADOOP-11697:
----------------------------------------

This is a trivial patch, thus no test included.

> The default value of {{fs.s3a.connection.timeout}} is {{50000}} milliseconds. It causes
many {{SocketTimeoutException}} when uploading large files using {{hadoop fs -put}}. 
> Also, the units for {{fs.s3a.connection.timeout}} and {{fs.s3a.connection.estaablish.timeout}}
are milliseconds. For s3 connections, I think it is not necessary to have sub-seconds timeout
value. Thus I suggest to change the time unit to seconds, to easy sys admin's job.
