Hi HBase devs, I've been trying to implement integration test for Bulkload replication. I'm using the already existing IntegrationTestBulkLoad as a base. My problem is actually running these tests. If I try to run them (tried multiple tests like Replication, BigLinkedList) with maven failsafe, I always get JVM outofmemory error every time it tries to create the mini cluster. I also tripled the default 4GB heap size. Looks like it's spanning few thousand threads, which explains the heap running out of memory.
Ultimately the whole test fails with a one liner saying: IntegrationTestBigLinkedList>IntegrationTestBase.setUp:170->setUpCluster:1840 ยป YarnRuntime I might have missed something. I also tried to run against an existing cluster, but had some trouble there either. In both cases, I followed the official HBase guide available at https://hbase.apache.org/book.html#hbase.tests I also found a few open issues just on Bulkload integration test: https://issues.apache.org/jira/browse/HBASE-12860 https://issues.apache.org/jira/browse/HBASE-14846 Is there something trivial I am missing? Does someone run these integration tests? If so, what is the key here? I could up the memory and timeout I guess, but I feel like I might be missing something here. Thanks! Norbert
