[Hadoop Wiki] Update of "Hive/HiveServer" by CarlSteinbach

Dear Wiki user,

You have subscribed to a wiki page or wiki category on "Hadoop Wiki" for change notification.

The "Hive/HiveServer" page has been changed by CarlSteinbach:
http://wiki.apache.org/hadoop/Hive/HiveServer?action=diff&rev1=10&rev2=11

  
  NOTE:
  
-  * The HiveServer is currently single threaded, which could present serious use limitations. See [[http://issues.apache.org/jira/browse/HIVE-80|JIRA: HIVE-80]].
+  * !HiveServer is multithreaded and was designed to support multiple concurrent client connections. However, there is currently no test coverage for this scenario. If you want to play it safe we recommend running one HiveServer process per client connection. Please see [[http://issues.apache.org/jira/browse/HIVE-80|JIRA: HIVE-80]] for more information.
   * Hive server and clients communicates through Thrift and FB303 services. In some distributions, both the Hadoop and Hive distributions have different versions of libthrift.jar and libfb303.jar. If they are incompatible, it may cause Thrift connection error when running the unit test on standalone mode. The solution is to remove the Hadoop's version of libthrift.jar and libfb303.jar.
