I've been manually experimenting running (nightly) tests on java9 (build
9-ea+157) with {{tests.disableHdfs=false}} and I've yet to encounter any test
failures.
I suspect maybe this change was a mistake? perhaps what Uwe was seeing was a
lot of failures realted to classes in hadoops java package due to other bugs
like SOLR-8876 & SOLR-10199 -- which don't always use HDFS, and now have their
own {{assumeFalse(JRE_IS_MINIMUM_JAVA9)}} logic.
[~thetaphi] -- do you remember the specific motivations for the
{{tests.disableHdfs=true if java9}} change? do any tests fail for you on your
java9 install if you revert that?
> diagnose HDFS test problems with Java9 and/or re-enable these tests

> As part of SOLR-8874, Uwe disabled all HDFS based tests under java9 at the
> build.xml/pom.xml level by adding a conditional to the existing
> {{tests.disableHdfs}} system property (Note: this property exists so that
> HDFS tests can be disabled by default on windows, but still run on cygwin if
> users wish to set that property)
> We need to get to the bottom of what exactly the issue(s) are with HDFS and
> file specific bugs to track the problems
