Hi,
I encounter this problem today. Luckily I find a way to reproduce this problem. I can reproduce this problem on both linux jdk1.8 and windows jdk1.8, with master branch. The key to reproducing, is to test UnseqTsFileRecoverTest (or SeqTsFileRecoverTest) AFTER first testing an integration test under the test/java/org/apache/iotdb/db/integration directory, such as IoTDBAuthorizationIT. The complete commands, to reproduce this problem, are: ``` git clone https://github.com/apache/incubator-iotdb.git cd incubator-iotdb mvn clean install -Dmaven.test.skip=true cd server mvn test -Dtest=org.apache.iotdb.db.integration.IoTDBAuthorizationIT,org.apache.iotdb.db.writelog.recover.UnseqTsFileRecoverTest ``` The error information on linux jdk1.8 and windows jdk1.8 are copied to the end of this email. It seems that something goes wrong with the common framework of these integration tests, which can lead to the NullPointerException in the following UnseqTsFileRecoverTest (or SeqTsFileRecoverTest). But I haven't found the exact cause. I might need some help.
