If I understand correctly, you'll just want to package your implementation
with your preference of project manager (maven, sbt, etc.) which registers
your dialect implementation into JdbcDialects, and pass the jar and let end
users load the jar. That will automatically do everything and they can
Not sure, too.
Can't you use Spark Packages for your scenario?

I am not so sure about it too. I think it is enough to expose JDBCDialect
as an API (which seems already is).
It brings some overhead to dev (e.g., to test and review PRs related to
another third party).
Such third party integration might better exist as a third party library

It's latter, and it also helps simplifying built-in data sources as well

Nice, thanks for the answer! I'll craft a PR soon. Thanks again.

Thank you all. I'll make a PR to Apache Spark website.
Bests,

Recapping today's sync on the wider dev list for visibility:
The original proposals here can be refactored into 3 distinct changes which
could be integrated iteratively. In order of decreasing priority:
1. Allow MapStatus to take an arbitrary/opaque payload and rip out hard
references to
My moderately informed take is that the "Hadoop 2.7" build is really a
"Hadoop 2.x" build and AFAIK should work with 2.8, 2.9, but, I
certainly haven't tested it nor have the PR builders. Just use the
"Hadoop provided" build on your env. Of course, you might well want to
use Hadoop 3.x (3.2.x
Hi,
We've been considering using the download package Spark 2.4.4 that's
pre-built for Hadoop 2.7 with Hadoop 2.7.7.
When used with Spark, Hadoop 2.7 is often quoted as the most stable.
However, Hadoop 2.7.7 is End Of Life. The most recent Hadoop vulnerabilities
have only been fixed in versions
It kind of already is. I was able to build the VerticaDialect as a sort of
plugin as follows:
Check out apache/spark tree
Copy in VerticaDialect.scala
Build with “mvn -DskipTests compile”
package the compiled class plus companion object into a JAR
Copy JAR to jars folder in Spark binary
Can we make the JDBCDialect a public API that users can plugin? It looks
like an end-less job to make sure Spark JDBC source supports all databases.

You can follow how we test the other JDBC dialects. All JDBC dialects
require the docker integration tests.

Hi, to answer both questions raised:
Though Vertica is derived from Postgres, Vertica does not recognize type names
TEXT, NVARCHAR, BYTEA, ARRAY, and also handles DATETIME differently enough to
cause issues. The major changes are to use type names and date format
supported by Vertica.

How can the dev community test it?

It's probably OK, IMHO. The overhead of another dialect is small. Are
there differences that require a new dialect? I assume so and might
just be useful to summarize them if you open a PR.

I'll leave this thread for early tomorrow so that someone in US timezone
can chime in, and craft a patch if no one objects.
