Hi Norbert Kalmar You mean run the test by the command: mvn test -Dtest=IntegrationTestBigLinkedList ? Then I think it should have some detail logs under your directory: <hbase-project>/hbase-it/target/surefire-reports
Aslo there should be some logs under you hbase-it/target/MiniCluster-xxx directory...
