Nick Dimiduk commented on HBASE-24086:
--------------------------------------
bq. Just curious, did you set the following config in hdfs-site and it still
doesn't work?
[~bharathv] no, I was not aware that we expect standalone mode to be broken out
of the box.
This was not the case before bumping the minimum hadoop version to 2.10,
because before that, stream capability was not exposed in the HDFS api, and
thus we'd proceed without. The patch I've posted removes the requirement of
manual configuration.
