Insufficient space for shared memory file

Insufficient space for shared memory file

New Contributor

Hello All,

 

We are using cloudera 5.10

 

When i am ruining hive quries  i am facing this warning Insufficient space for shared memory file .

 

After few tries it throws: Exception in thread "main" java.io.IOException: No space left on device

 

My Query fails !!

 

Finally tried to debug , got some intersting things to ask .

 

The data node in which the query was executing has 

 

/dev/mapper/vgroot-tmp   100% usage   mounted on /tmp

 

Now 

 

Where exactly the hive stores the temporary/intermediate data sets when executing?

1) Its in hdfs or edge node 

2) what is /dev/mapper/vgroot-tmp  

 

Again when it ran on the same node with /dev/mapper/vgroot-tmp   100% usage it ran successfully .

 

 

Help Appreciated .
