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
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 .
