HI ALL,
I setup Cassandra on a linux host.
I have insert some data into “mykeyspace.cffex_l23” table.
The following error are raised during query data from “mykeyspace.cffex_l23”.
Could you give me any suggestion to fix it?
According to “top” cmd, I found that most of the memory are used by Cassandra.
Cpu(s): 0.0%us, 0.1%sy, 0.0%ni, 99.9%id, 0.0%wa, 0.0%hi, 0.0%si, 0.0%st
