pool, DataFrame Reader's not closing S3 connections?
Brady Auen created SPARK-17544:
----------------------------------
Summary: Timeout waiting for connection from pool, DataFrame Reader's not closing S3 connections?
Key: SPARK-17544
URL: https://issues.apache.org/jira/browse/SPARK-17544
Project: Spark
Issue Type: Bug
Components: Input/Output
Affects Versions: 2.0.0
Environment: Amazon EMR, S3, Scala
Reporter: Brady Auen
I have an application that loops through a text file to find files in S3 and then reads them in, performs some ETL processes, and then writes them out. This works for around 80 loops until I get this:

I don't use Amazon's API, I'm only use DataFrameReader's and DataFrameWriters, and I suspect that previous connections aren't being closed and so after a fixed amount of iterations the connection pool is exhausted
