Socket Leaks in Hive 0.8

[Subroto]

Hi, When I try to close my HiveMetaStoreClient, it fails. Following is the code snippet from Hive code base which is responsible for closing the connection. public void close() {     isConnected = false;     if ((transport != null) && transport.isOpen()) {       transport.close();     }     try {       if (null != client) {         client.shutdown();       }     } catch (TException e) {       // TODO:pc cleanup the exceptions       LOG.error("Unable to shutdown local metastore client");       LOG.error(e.getStackTrace());       // throw new RuntimeException(e.getMessage());     } When client.shutdown() is called, it throws an exception: org.apache.thrift.transport.TTransportException: Cannot write to null outputStream Further the logging of error also mask the actual error. The logging just prints the Array object of stack-trace; hiding the actual problem. Following are the logs: ERROR [2012-08-09 15:36:04] (HiveMetaStoreClient.java:288) - Unable to shutdown local metastore client ERROR [2012-08-09 15:36:06] (HiveMetaStoreClient.java:289) - [Ljava.lang.StackTraceElement;@8250825 Please let me know if I am making any mistake while closing the HiveMetaStoreClient.
