Nope. Actually i am reading some zip files using the sc.binaryfiles from spark. But after some 100th file read it gets hangs indefinitely. I was monitoring the opened connection of every spark binary file read. None of the connections were closed after every read of each binary files. Yes I am sure it is a not a network or S3 issue. Spark version - 2.2.0/ Hadoop version -2.7.3

> Hi,
> I am using Spark 2.2.0(recent version) to read binary files from S3. I use sc.binaryfiles to read the files.
> It is working fine until some 100 file read but later it get hangs indefinitely from 5 up to 40 mins like Avro file read issue(it was fixed in the later releases)
> I tried setting the fs.s3a.connection.maximum to some maximum values but didn't help.
> And finally i ended up using the spark speculation parameter set which is again didnt help much.
> One thing Which I observed is that it is not closing the connection after every read of binary files from the S3.
> example :- sc.binaryFiles("s3a://test/test123.zip")
> Please look into this major issue!
