--------------------------------------
[~wesmckinn] Thanks for your response!
I found https://issues.apache.org/jira/browse/ARROW-3957 and the PR that
address it:
[https://github.com/apache/arrow/commit/758bd557584107cb336cbc3422744dacd93978af].
Seems like the cause of the issue is an incorrect port? The default to
{{pa.hdfs.connect()}} is {{port=0}}. What would be the correct port to use?

> Project: Apache Arrow
> Issue Type: Bug
> Components: Python
> Affects Versions: 0.14.1
> Reporter: Saurabh Bajaj
> Priority: Minor
>
> I'm running a Dask-YARN job that dumps a results dictionary into HDFS (code
> shown in traceback below) using PyArrow's HDFS IO library. However, the job
> intermittently runs into the error shown below, not every run, only
> sometimes. I'm unable to determine the root cause of this issue.
