---------------------------------------
[~jerryshao] Yes, it's in HA mode. Updating to newer HDFS is not an option in
our infrastructure, unfortunately. PR you reference is outdated at the moment -
I've tried to crudely apply it with my limited knowledge of the mechanism, but
it seems that the issue persists. Possibly a mistake on my side, would be great
if someone could update the fix.

> doesn't work in newer version of Hadoop. This seems to be cause by a move of
> property name from {{fs.hdfs.impl}} to {{fs.AbstractFileSystem.hdfs.impl}}
> which happened somewhere around 2.7.0 or earlier. Taking this into account
> should make workaround work again for less recent Hadoop versions.
