Szehon Ho commented on HIVE-13491: ---------------------------------- I was also thinking the other day that maybe the machines are getting loaded or somewhat slow, hence HMS cannot start up in time. But this will tell us for certain. I will also take a look at that if I get a chance. > Testing : log thread stacks when metastore fails to start > ---------------------------------------------------------- > > Key: HIVE-13491 > URL: https://issues.apache.org/jira/browse/HIVE-13491 > Project: Hive > Issue Type: Bug > Components: Test, Testing Infrastructure > Reporter: Thejas M Nair > Assignee: Thejas M Nair > Attachments: HIVE-13491.1.patch > > > Many tests are failing in ptest2 because metastore fails to startup in the > expected time. > There is not enough information to figure out why the metastore startup > failed/got hung in the hive.log file. Printing the thread dumps when that > happens would be useful for finding the root cause. > The stack in test failure looks like this - > {code} > java.net.ConnectException: Connection refused > at java.net.PlainSocketImpl.socketConnect(Native Method) > at > java.net.AbstractPlainSocketImpl.doConnect(AbstractPlainSocketImpl.java:339) > at > java.net.AbstractPlainSocketImpl.connectToAddress(AbstractPlainSocketImpl.java:198) > at > java.net.AbstractPlainSocketImpl.connect(AbstractPlainSocketImpl.java:182) > at java.net.SocksSocketImpl.connect(SocksSocketImpl.java:392) > at java.net.Socket.connect(Socket.java:579) > at > org.apache.hadoop.hive.metastore.MetaStoreUtils.loopUntilHMSReady(MetaStoreUtils.java:1208) > at > org.apache.hadoop.hive.metastore.MetaStoreUtils.startMetaStore(MetaStoreUtils.java:1195) > at > org.apache.hadoop.hive.metastore.MetaStoreUtils.startMetaStore(MetaStoreUtils.java:1177) > at > org.apache.hadoop.hive.thrift.TestHadoopAuthBridge23.setup(TestHadoopAuthBridge23.java:153) > at > org.apache.hadoop.hive.thrift.TestHadoopAuthBridge23.testMetastoreProxyUser(TestHadoopAuthBridge23.java:241) > {code} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
