-----------------------------------
Summary: Improve Hadoop test sanity checks
Key: SOLR-14048
URL: https://issues.apache.org/jira/browse/SOLR-14048
Project: Solr
Issue Type: Test
Security Level: Public (Default Security Level. Issues are Public)
Components: Hadoop Integration, hdfs, Tests
Reporter: Kevin Risden
Add more checks around the Hadoop modified classes we use.
Some ideas from [~hossman]
* some dev docs (package level javadocs?) explaining the whole
{{org.apache.hadoop}} "shadow" class impls
* ideally include some hook in {{HdfsTestUtil}} that causes it to fail fast if
it can detect that the classloader didn't pick up our modified classes? ..
maybe by adding a new {{public static final Object
SOLR_HACK_FOR_CLASS_VERIFICATION = new Object}} to each
{{org.apache.hadoop.\*\*}} that it could check for via reflection?
