Uwe Schindler commented on SOLR-11261:
--------------------------------------

Unfortunately, with this commit they introduced a new dependency for tests: - sorry for not seeing this (I did run tests, but on Windows not everything is executed) https://github.com/apache/hadoop/commit/1d017040605b64c7092d8e83d057f4427044aa87

I have to add another old Mortbay-Jetty dependency for tests. I will check again.

> In SOLR-10966 we added a "bad" workaround to prevent Hadoop's Shell class from breaking with Java 9 (StringIndexOutOfBoundsException). This was resolved in Hadoop 2.7.4, released a few weeks ago. We should revert the bad hack and update Hadoop.
> After running tests, I see no issue with the bugfix relaese.
> I will commit to master and 7.x and once it settled, I will backport. If we can't get this into 6.6.1, it's not so bad, but then we have to live with the "bad" hack there.
