[jira] [Commented] (SPARK-22255) FileAppender InputStream.read() timeout and blocking state

    [ https://issues.apache.org/jira/browse/SPARK-22255?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16200732#comment-16200732 ] 

Sean Owen commented on SPARK-22255:
-----------------------------------

You have to block here, right? I'm not clear how you wait on input if you only check available(). There will be points where there are 0 input bytes available but you don't want to stop.

> 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.
