[jira] [Commented] (HIVE-11681) sometimes when query mr job
progress, stream closed exception will happen
[ https://issues.apache.org/jira/browse/HIVE-11681?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14736752#comment-14736752 ]
wangwenli commented on HIVE-11681:
----------------------------------
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
