Hi Sandra,
The UDF template repo that you used was outdated for some time. There has
been some UDF refactorization in AsterixDB since that. I've just updated
the template repo to the latest AsterixDB build. Please pull the latest
changes before you try again.
If you want to install UDF with the NCService deployment, you would have to
manually copy the package content into the
"lib/udfs/DATAVERSE_NAME/LIB_NAME/" directory. You will probably need to
create all the folders including the "udfs" one. A sample structure of the
lib directory will be like this:
lib
....
├── stax-utils-20060502.jar
└── udfs
└── test
└── testlib
├── asterix-udf-template-0.1-SNAPSHOT.jar
└── library_descriptor.xml
About your previous question, Ansible always relies on SSH even if you
configure it with localhost only. It treats the localhost as a cluster with
a single machine. You may want to check the password-less configuration of
your machine to avoid that problem. If you just to want to find a fast way
to play around, the NCService deployment would be the right way to go. :)
Best,
Xikui
