All the scalar fields coming out of HBase are of VARBIARY type and hence
input type (field Param) will be passed in a VarBinaryHolder.
Please take a look at similar function implementations[1] which decode
primitive types encoded using HBase OrderedBytes encoding.

Hi,
I'm trying to deploy a UDF that I have written according to the
documentation.
I have also:
1. Copied the jar file
to jars/3rdparty
2. Changed the config "conf/drill-override.conf" to include:
drill.logical.function.package +=
["org.apache.drill.exec.expr.fn.impl","com.activi
Did you include a file drill-module.conf in your jar along with source
files?

Hi Jim,
Now I have added the file to the jar (both root and resources folder) but
that does not seem to change anything.
Any additional ideas?

Hi again,
Going over the documentation once more I came across this:
- Add the sources and classes JAR files to Drill’s classpath.
I'm only including a standard .jar (with classes no sources) and I wonder
why this dependency is listed.
Anyways, that it the next step.
A sample .jar that work
Hi,
Building it using the maven-source-plugin (source:jar) and copying that
.jar file over to "drill/jar/3rdparty" changes nothing :(.
The .jar file now includes the empty drill-module.conf missing earlier.
This is all getting a tiny bit frustrating and any additional assistance is
welcomed :).
Maven will typically create a jar for class and a jar for source when told
to do so. I just include the source files in the same jar as the class
files. There is a github example drill udf project we are working on to
include several examples to simplify the learning curve. If your
interested... I'
Hi Jim,
My UDF is currently so simple that I'm not sure you need it (or want it).
It basically just rounds a timestamp value with ISO 8601 periods
asRoundTimestamp(timestampvalue,'PT10M').
I would be more than happy to contribute to your project rather than
building our own :).
Is the repo publ
Sounds like a fine example, not because of sophistication but because it deals
with dates.
Check the drill logs. It is likely that drill is grumpy about something in
your udf or packaging.
Also, feel free to snitch the pom from the simple examples in order to get the
pieces assembled and
Hi Jim,
I'm still not able to make this work. Do you have a sample .jar file with a
small example that you are running?

Have you seen this github project:

Hi Ted,
I fetched this, built it and deployed it without problems.
I can not see any real difference other than this deploys two .jar (I tried
that as well earlier).
I'm still trying to figure out why Drill is not picking up my UDFs

Hi Stefan,
Do you think you can share your complete project ?
This will help to debug it for you.

Hi,
I'm more than happy to share the little that is there (I will publish it on
github and send link tomorrow).
I ended up copying my UDF (singl-file.java) into the simple-drill-function
project where it got picked up.
Then I discovered a whole new set of dependencies/limitations

I pulled out your udf class and threw it into my package. It worked for me
with a few modifications.
You can not have imported classes or method references in your eval or
setup methods as the code will get pulled out and executed somewhere else
and it won't be able to find it. With that in mind,
And if you want lots of (boringly identical) rows:
WITH x AS ( SELECT * FROM ( VALUES 1,1,1,1,1,1,1,1,1,1 ) AS MyTable( key ) )
SELECT COUNT(*)
FROM x AS x1
INNER JOIN x AS x2 on x2.key = x1.key
INNER JOIN x AS x3 on x3.key = x2.key
INNER JOIN x AS x4 on x4.key = x3.key
INNER JOIN x AS x5 on x5

You are very correct on this. The purpose of the simple drill function is
