Phoenix UDF jar cache?

[Randy Hu <ru...@gmail.com>]

Developed and test UDF successfully, but was surprised that the same SELECT
with UDF still succeeded after the jar was removed. Same behavior after
restart sqlline.py, even HBase. So is there a permanent cache for UDF jars
on disk in Phoenix?

So far not causing any problem yet, but a little bit concerned since the jar
is likely rebuilt multiple times during the development. Want to make sure
Phoenix always pick up the latest version.

Thanks

Yes, this is a limitation[1] of the current implementation of UDF  and
class loader used. It is recommended either to reboot the cluster if
implementation changes or use new jar name.
