[petacube]

https://arrow.apache.org/docs/python/generated/pyarrow.HdfsFile.html#pyarrow.HdfsFile.readlines
see above docs but in pyarrow 0.10.0 hdfsFile object does not implement either readline or readlines

what am i to make out of this?

The documentation should be amended to indicate that it is not implemented.

Patches welcome: https://github.com/apache/arrow/blob/master/python/pyarrow/io.pxi#L317
