Hi, We have recently upgraded from 5.11.2 to 5.14.2. The upgrade was untill we identified that many databases were not visible/loaded in navigator. The logs have below. Any related pointers are welcome. 2018-08-31 10:12:17,344 ERROR com.cloudera.nav.hive.extractor.AbstractHiveExtractor [CDHExecutor-0-CDHUrlClassLoader@7fbf5fdd]: Failed to extract database dummy_database with error: java.net.SocketException: Broken pipe (Write failed) org.apache.thrift.transport.TTransportException: java.net.SocketException: Broken pipe (Write failed) at org.apache.thrift.transport.TIOStreamTransport.write(TIOStreamTransport.java:147) at org.apache.thrift.transport.TTransport.write(TTransport.java:107) at org.apache.thrift.transport.TSaslTransport.writeLength(TSaslTransport.java:391) at org.apache.thrift.transport.TSaslTransport.flush(TSaslTransport.java:499) at org.apache.thrift.transport.TSaslClientTransport.flush(TSaslClientTransport.java:37) at org.apache.hadoop.hive.thrift.TFilterTransport.flush(TFilterTransport.java:77) at org.apache.thrift.TServiceClient.sendBase(TServiceClient.java:73) at org.apache.thrift.TServiceClient.sendBase(TServiceClient.java:62) at org.apache.hadoop.hive.metastore.api.ThriftHiveMetastore$Client.send_get_database(ThriftHiveMetastore.java:664) at org.apache.hadoop.hive.metastore.api.ThriftHiveMetastore$Client.get_database(ThriftHiveMetastore.java:656) at org.apache.hadoop.hive.metastore.HiveMetaStoreClient.getDatabase(HiveMetaStoreClient.java:1213) at com.cloudera.nav.hive.extractor.AbstractHiveExtractor.extractDatabase(AbstractHiveExtractor.java:147) at com.cloudera.nav.hive.extractor.AbstractHiveExtractor.extractDatabases(AbstractHiveExtractor.java:133) at com.cloudera.nav.hive.extractor.HiveExtractor.run(HiveExtractor.java:63) at com.cloudera.nav.hive.extractor.AbstractHiveExtractor.run(AbstractHiveExtractor.java:118) at com.cloudera.nav.hive.extractor.HiveExtractorShim.run(HiveExtractorShim.java:35) at com.cloudera.cmf.cdhclient.CdhExecutor$RunnableWrapper.call(CdhExecutor.java:221) at com.cloudera.cmf.cdhclient.CdhExecutor$RunnableWrapper.call(CdhExecutor.java:211) at com.cloudera.cmf.cdhclient.CdhExecutor$CallableWrapper.doWork(CdhExecutor.java:236) at com.cloudera.cmf.cdhclient.CdhExecutor$SecurityWrapper$1.run(CdhExecutor.java:189) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:422) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1917) at com.cloudera.cmf.cdh5client.security.UserGroupInformationImpl.doAs(UserGroupInformationImpl.java:44) at com.cloudera.cmf.cdhclient.CdhExecutor$SecurityWrapper.doWork(CdhExecutor.java:186) at com.cloudera.cmf.cdhclient.CdhExecutor$1.call(CdhExecutor.java:125) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:748) Caused by: java.net.SocketException: Broken pipe (Write failed) at java.net.SocketOutputStream.socketWrite0(Native Method) at java.net.SocketOutputStream.socketWrite(SocketOutputStream.java:111) Thanks
