Status of solR / HDFS-v3 compatibility

Hi

solr doc [1] says it's only compatible with hdfs 2.x
is that true ?

We have some Solr 7.6 setups connecting to HDFS 3 clusters. So far that
did not show any compatibility problems.

For Apache Solr 7.x or older yes - Apache Hadoop 2.x was the dependency.
Apache Solr 8.0+ has Hadoop 3 compatibility with SOLR-9515. I did some
testing to make sure that Solr 8.0 worked on Hadoop 2 as well as Hadoop 3,
but the libraries are Hadoop 3.

The reference guide for 8.0+ hasn't been released yet, but also don't think
it was updated.
