----------------------------------

below is the stacktrace  that stream be cached in the URLClassloader when load 
TaskCounter.properties in hadoop-mapreduce-client-core.jar

below is the stacktrace that steam is closed:
java.util.zip.InflaterInputStream.getStack(InflaterInputStream.java:309)
java.util.zip.InflaterInputStream.close(InflaterInputStream.java:247)
java.util.zip.ZipFile$ZipFileInflaterInputStream.close(ZipFile.java:398)
java.util.zip.ZipFile.close(ZipFile.java:585)
sun.net.www.protocol.jar.URLJarFile.close(URLJarFile.java:167)
java.net.URLClassLoader.close(URLClassLoader.java:294)
org.apache.hadoop.hive.common.JavaUtils.closeClassLoader(JavaUtils.java:101)
org.apache.hadoop.hive.common.JavaUtils.closeClassLoadersTo(JavaUtils.java:79)
org.apache.hadoop.hive.ql.session.SessionState.close(SessionState.java:942)
org.apache.hive.service.cli.session.HiveSessionImpl.close(HiveSessionImpl.java:562)


so here the root cause is that:  add jar will lead to new classloader created, 
and it will cache the JarFile ,  but JarFile in jvm only has one instance(see 
JarURLConnection.setUseCache), so when other thread is read from the same 
JarFile, once hive session closed will lead to classloader close the stream.

> sometimes when query mr job progress, stream closed exception will happen

> after analysis, we found the root cause, below is step to reproduce the issue
> 1.  open one beeline window, add jar
> 2.  execute one sql like create table abc as select * from t1;
> 3.  execute !quit, before this add a breakpoint at 
> java.net.URLClassLoader.close(), so it will stop here
> 4. open another beeline window
> 5. execute one sql like select count(*) from t1, before this add one 
> condition breakpoint at org.apache.hadoop.conf.Configuration.parse, the 
> condition is 
> url.toString().indexOf("hadoop-mapreduce-client-core-V100R001C00.jar!/mapred-default.xml")>0
> 6. when proceed to the above step, just get the stream
> 7. let the 3th step go ahead, which will close the stream
> 8. now, let sixth step go ahead, then the above exception coming
> suggest solution:
> the issue is hadppend when client use add jar + short connection ,  the 
> client app should try best to use long connection, means reuse hive connetion
> meanwhile, here ,experts can suggest good solution for this issue
