chenjianxun commented on HIVE-16220:
------------------------------------

is there any progess for this issue?

i have got the same problem, the instances of 
"org.apache.hadoop.hive.conf.HiveConf" keep growing.

and the dump file of hiveserver2 shows that there is a memory leak problem.

 

 

Leak Suspects
1,041 instances of *"org.apache.hadoop.hive.conf.HiveConf"*, loaded by 
*"sun.misc.Launcher$AppClassLoader @ 0xeaaa0058"* occupy *270,268,056 (52.70%)* 
bytes. These instances are referenced from one instance of 
*"java.util.HashMap$Node[]"*, loaded by *"<system class loader>"*

> Memory leak when creating a table using location and NameNode in HA

>             Project: Hive
>          Issue Type: Bug
>          Components: HiveServer2
>    Affects Versions: 1.2.1
>         Environment: HDP-2.4.0.0
>            Reporter: Angel Alvarez Pascua
>            Priority: Major
>
> The following simple DDL
> CREATE TABLE `test`(`field` varchar(1)) LOCATION 
> 'hdfs://benderHA/apps/hive/warehouse/test'
> ends up generating a huge memory leak in the HiveServer2 service.
> After two weeks without a restart, the service stops suddenly because of 
> OutOfMemory errors.
> This only happens when we're in an environment in which the NameNode is in 
> HA,  otherwise, nothing (so weird) happens. If the location clause is not 
> present, everything is also fine.
> It seems, multiples instances of Hadoop configuration are created when we're 
> in an HA environment:
> <AFTER ONE EXECUTIONS OF CREATE TABLE WITH LOCATION>
> 2.618 instances of "org.apache.hadoop.conf.Configuration", loaded by 
> "sun.misc.Launcher$AppClassLoader @ 0x4d260de88" 
> occupy 350.263.816 (81,66%) bytes. These instances are referenced from one 
> instance of "java.util.HashMap$Node[]", 
> loaded by "<system class loader>"
> <AFTER TWO EXECUTIONS OF CREATE TABLE WITH LOCATION>
> 5.216 instances of "org.apache.hadoop.conf.Configuration", loaded by 
> "sun.misc.Launcher$AppClassLoader @ 0x4d260de88" 
> occupy 699.901.416 (87,32%) bytes. These instances are referenced from one 
> instance of "java.util.HashMap$Node[]", 
> loaded by "<system class loader>"
