Analysis
TBD - More work hereThis test does not fail every time.
The test:
- creates a LuceneIndex in 3 servers on an older version servers
- rolls each server one at a time and:
- creates the region
- executes a query
- verifies the results
The LuceneQueryImpl.findKeys method causes LuceneQueryFunction to be invoked in an older member. That older member tries to create an IndexWriter and fails.
The exception in the older member is:

public IndexInput openInput(String name, IOContext context) throws IOException {

The FileSystem.getFile method does a get on the fileAndChunkRegion:

final File file = (File) fileAndChunkRegion.get(name); |
I'm not sure which File is being requested but all of the activity on that bucket is from current version vm0:

So, it looks like a newer version server with Lucene 7 puts a File into the fileAndChunkRegion, and an older version server with Lucene 6 gets it out and attempts to read it unsuccessfully.
Hydra Test Execution
The lucene.bt and backwardCompatibilityLucene.bt had only 1 hung test which I don't think was related to Lucene 7.x.
