Hi guys sorry for delay, I took a little look at it. Seems like test fail because in test environment TxnHandler is initialized more than once but not tearing down when shutdown. So everytime it makes more connection to database and eventually gets exhausted. Maybe I should just call TxnUtils.getTxnStore() instead. Actually found something else, in current version of Hive it is now on critical path of startup, since AcidMetricService is added to list of services in https://issues.apache.org/jira/browse/HIVE-24824: ``` setConf:369, TxnHandler (org.apache.hadoop.hive.metastore.txn) getTxnStore:124, TxnUtils (org.apache.hadoop.hive.metastore.txn) setConf:314, AcidMetricService (org.apache.hadoop.hive.metastore.metrics) startAlwaysTaskThreads:525, HMSHandler (org.apache.hadoop.hive.metastore) init:493, HMSHandler (org.apache.hadoop.hive.metastore) invoke0:-1, NativeMethodAccessorImpl (sun.reflect) invoke:62, NativeMethodAccessorImpl (sun.reflect) invoke:43, DelegatingMethodAccessorImpl (sun.reflect) invoke:498, Method (java.lang.reflect) invokeInternal:147, RetryingHMSHandler (org.apache.hadoop.hive.metastore) invoke:108, RetryingHMSHandler (org.apache.hadoop.hive.metastore) <init>:80, RetryingHMSHandler (org.apache.hadoop.hive.metastore) getProxy:93, RetryingHMSHandler (org.apache.hadoop.hive.metastore) newRetryingHMSHandler:133, HiveMetaStore (org.apache.hadoop.hive.metastore) invoke0:-1, NativeMethodAccessorImpl (sun.reflect) invoke:62, NativeMethodAccessorImpl (sun.reflect) invoke:43, DelegatingMethodAccessorImpl (sun.reflect) invoke:498, Method (java.lang.reflect) callEmbeddedMetastore:291, HiveMetaStoreClient (org.apache.hadoop.hive.metastore) <init>:205, HiveMetaStoreClient (org.apache.hadoop.hive.metastore) <init>:113, HiveMetaStoreClientWithLocalCache (org.apache.hadoop.hive.metastore) <init>:155, SessionHiveMetaStoreClient (org.apache.hadoop.hive.ql.metadata) newInstance0:-1, NativeConstructorAccessorImpl (sun.reflect) newInstance:62, NativeConstructorAccessorImpl (sun.reflect) newInstance:45, DelegatingConstructorAccessorImpl (sun.reflect) newInstance:423, Constructor (java.lang.reflect) newInstance:84, JavaUtils (org.apache.hadoop.hive.metastore.utils) <init>:101, RetryingMetaStoreClient (org.apache.hadoop.hive.metastore) getProxy:154, RetryingMetaStoreClient (org.apache.hadoop.hive.metastore) getProxy:125, RetryingMetaStoreClient (org.apache.hadoop.hive.metastore) createMetaStoreClient:5444, Hive (org.apache.hadoop.hive.ql.metadata) getMSC:5522, Hive (org.apache.hadoop.hive.ql.metadata) getMSC:5502, Hive (org.apache.hadoop.hive.ql.metadata) getAllFunctions:5810, Hive (org.apache.hadoop.hive.ql.metadata) reloadFunctions:337, Hive (org.apache.hadoop.hive.ql.metadata) registerAllFunctionsOnce:316, Hive (org.apache.hadoop.hive.ql.metadata) <init>:542, Hive (org.apache.hadoop.hive.ql.metadata) create:434, Hive (org.apache.hadoop.hive.ql.metadata) getInternal:421, Hive (org.apache.hadoop.hive.ql.metadata) get:377, Hive (org.apache.hadoop.hive.ql.metadata) createHiveDB:291, BaseSemanticAnalyzer (org.apache.hadoop.hive.ql.parse) <init>:269, BaseSemanticAnalyzer (org.apache.hadoop.hive.ql.parse) <init>:473, SemanticAnalyzer (org.apache.hadoop.hive.ql.parse) postInit:630, QTestUtil (org.apache.hadoop.hive.ql) evaluate:88, CliAdapter$1$1 (org.apache.hadoop.hive.cli.control) evaluate:20, RunRules (org.junit.rules) evaluate:306, ParentRunner$3 (org.junit.runners) run:413, ParentRunner (org.junit.runners) execute:365, JUnit4Provider (org.apache.maven.surefire.junit4) executeWithRerun:273, JUnit4Provider (org.apache.maven.surefire.junit4) executeTestSet:238, JUnit4Provider (org.apache.maven.surefire.junit4) invoke:159, JUnit4Provider (org.apache.maven.surefire.junit4) runSuitesInProcess:377, ForkedBooter (org.apache.maven.surefire.booter) execute:138, ForkedBooter (org.apache.maven.surefire.booter) run:465, ForkedBooter (org.apache.maven.surefire.booter) main:451, ForkedBooter (org.apache.maven.surefire.booter) ``` So seems it's a Hive 3 only bug?
