[jira] [Commented] (ARROW-6150) Intermittent Pyarrow HDFS IO error

["Wes McKinney (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-6150?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16901386#comment-16901386 ] 

Wes McKinney commented on ARROW-6150:
-------------------------------------

Our use of libhdfs is pretty straightforward, so the issue seems unlikely to be caused by a bug in the Arrow implementation. I've seen other reports of the errno 255, they might give some clue about what could be wrong with the job. If you find anything out (or a way to reliably reproduce) let us know

> 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.
