I'm trying to update elasticsearch dependencies and I'm blocked on hadoop-format HadoopFormatIOElasticTest.
The tests use elasticsearch emulator that is no longer supported as is said here: https://discuss.elastic.co/t/in-memory-testing-with-resthighlevelclient/106196/6 There is a test framework with ESSingleNodeTestCase but it has a jar hell check which crashes on compiling on both compile and testCompile sdks:java:core and I don't see an easy solution here. I tried to write my own JarHell class in org.elasticsearch.bootstrap package, but without success - the test gets into an infinite loop. The easiest solution would be to use testcontainers but then the test becomes an integration test - would it be acceptable to run such a test in Java Precommit? I also encountered a problem fixing HadoopFormatIOElasticIT test - the test assumes that there is an Elasticsearch instance already running with some data. But there is nowhere written what that data should look like. I suppose it's something like Txn_ID0, Txn_ID1 but I didn't manage to get testHifIOWithElastic test pass.
