Fwd: reading hbase configuration properties in user defined functions

Hi guys,



I need to connect to zookeeper quorum and read data from zNode from a user
defined function.

I am able to connect by adding the zookeeper quorum and path of zNode in
hbase-site.xml (clinet side).Is there a way to load the zookeeper quorum
properties from hbase-site.xml (hbase configuration server side) or any
alternative solutions?



Thanks

venu

Hi Venu,
Do you mean that you'd connect to zookeeper and read from zNode from a
Phoenix UDF? That sounds dangerous as a UDF gets executed for every row
when used in a WHERE clause during scanning and filtering from a region
server.
Thanks,
James
