Eli Collins commented on HDFS-3263:
-----------------------------------
bq. TUCU: No we cannot, the current mechanism relies on having the
HADOOP_CONF_DIR in the classpath. HttpFS does not have HADOOP_CONF_DIR in the
classpath (furthermore, it can run in a setup where there is no other hadoop
component installed)
I was thinking that it might make sense to keep the mechanism the same so that
we don't have two separate ways to specify the conf dir (a HADOOP_CONF_DIR env
dir being the normal way hadoop clients locate config vs the new "config.dir"
parameter that essentially does the same). I don't feel strongly.
bq. TUCU: was not aware of the hadoop-policy.xml but how would the be used in
HttpFS context?
I checked and it looks like all the relevant keys are only used on the server
side so I don't think you need to include it here.
bq. This check is to prevent httpfs code (got bitten by this) to create and use
a Configuration object without the hadoop confs in it (per first bullet item)
Makes sense.
+1 modulo the following nits
Nit: How about renaming "config.dir" to "hadoop.conf.dir"
Nit: HttpFSServerWebApp line is way over 80 chars now, please re-format
> HttpFS should read HDFS config from Hadoop site.xml files

> Currently HttpFS reads HDFS client configuration from the httfs-site.xml from
> any property of the form 'httpfs.hadoop.conf:HADOOP_PROPERTY'
> This is a bit inconvenient.
> Instead we should support a single property 'httpfs.hadoop.configuration.dir'
> that can be pointed to HADOOP conf/ dir and the core-site.xml and
> hdfs-site.xml files would be read from there.
