------------------------------------
Summary: Intermittent Pyarrow HDFS IO error
Key: ARROW-6150
URL: https://issues.apache.org/jira/browse/ARROW-6150
Project: Apache Arrow
Issue Type: Bug
Components: Python
Affects Versions: 0.14.1
Reporter: Saurabh Bajaj
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.

correct HDFS RPC port}}
