-------------------------------------
{quote}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.
{quote}
So as of today, what configuration that user need to set for
hbase.dynamic.jars.dir, in order to restrict that only the jar from the local
filesystem (not the network) is able to load in ?
> Support restriction of remote UDF load sources

> 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.
