-------------------------------
Resolution: Not A Problem
> SPARK-22255 FileAppender InputStream Read timeout and blocking state
> --------------------------------------------------------------------
>
> Key: SPARK-22255
> URL: https://issues.apache.org/jira/browse/SPARK-22255
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 2.2.0
> Reporter: Mariusz Galus
> Priority: Minor
>
> The FileAppender logic when reading from InputStream blocks. This can be simply avoided with a InputStream.available() check prior to reading.
> If this is done, a variable for estimated available bytes needs to be instantiated to use in the conditionals. The conditional for reading from the inputstream and the conditional for appending to the file.
