Thanks for your reply.  But all the datanote disk has more than 50% space empty

Thanks and Regards

no space left on device can also mean that one of your datanode disk is full.

Can you check disk used by each datanode.

May be you will need to rebalance your replication so that some space is made free on this

When I run a query in Hive, I get below exception.  I noticed the error “No space left on

Then I did “hadoop fs -count -q /var/local/hadoop” – which gave below output

none             inf            none             inf           69          275          288034318

Why I am getting none and inf for space and remaining space quota?  Is this meaning is unlimited
space or is there is any space left?

I tried “hadoop dfsadmin -setSpaceQuota 100G /var/local/hadoop”  --  Not sure 100G is
correct or not?  How much I need to set and how to calculate this?

After setting 100G , I get the below output  for “hadoop fs -count -q /var/local/hadoop”

none             inf    107374182400    104408308039           73          286          297777777

I have to wait to see whether 100G is going to give me an exception or not….
