Ethan Wang commented on PHOENIX-4231:
-------------------------------------
To summarize what we are going to be working on this jira: As of today, loading
from add jars 'XX' allows loading the jars from any hdfs network location to
local's hbase.dynamic.jars.dir. So we are now going to make addition features
to PHOENIX-1890 so that:
when a property, say "loading.from.network.allowed" property is configured as
false, "add jars" command only restricted to load from local file system or
local hdfs.
Is the plan above accurate?

Once this feature is done. user will be doing the following for creating a Udf:
Add jars hdfs://localhost/udf.jar
CREATE FUNCTION func(VARCHAR) returns VARCHAR as 'com.example.test.udfFunc'
using jar 'configured/hbase/dynamic/jars/dir/udf2.jar'
> Support restriction of remote UDF load sources

> Project: Phoenix
> Issue Type: Improvement
> Reporter: Andrew Purtell
> Assignee: Chinmay Kulkarni
> Priority: Major
>
> When allowUserDefinedFunctions is true, users can load UDFs remotely via a
> jar file from any HDFS filesystem reachable on the network. The setting
> hbase.dynamic.jars.dir can be used to restrict locations for jar loading but
> is only applied to jars loaded from the local filesystem. We should
> implement support for similar restriction via configuration for jars loaded
> via hdfs:// URIs.
