Re: Cassandra nodes on EC2 in two different regions not communicating

[Peter Fales]

Are you running nodetool on the host, or on a remote machine? 

If local, does "netstat -n" show that you are listening on the JMX port?

If remote, have you added the JMX port to your security group?

disk (sstable file, index and BF) layout

[Mimi Aluminium]

Hi,
Can you please help me in modeling the disk layout.
I am estimating  the size of the sstable file, index and BF (for a certain
data model) using the details in ths link
http://wiki.apache.org/cassandra/ArchitectureSSTable and compare it with the
real DB files.
Unfortunately, there is a mismatch between the estimated size and real file.
Does the timestamp field is allocated even if no value was assigned to it?
The real index file row is much larger than what is described, and the
structure of the column index is not clear.
Can you give me more details about the index file, column index and BF size?

Please can you refer me to the code where those field are written to the
disk?
Thanks a lot,
Miriam
