Andrei Savu commented on WHIRR-351:
-----------------------------------
I'm seeing {{chown: invalid user: `mapred:mapred'}} when running the
services/hadoop integration tests. I guess this user only exists for CDH.
> configure_hadoop should create+chown all data dirs listed in
> hadoop-hdfs.dfs.data.dir

> If the directories listed in dfs.data.dir do not exist,
> the datanodes will try to create them. This fails if the hadoop user
> has sufficient permissions.
> To avoid the problem, the directories should be created before starting the
> datanodes.
