Cassandra adding node issue (no UJ status)

I logged the open files every 10 mins, last record is : lsof -p $cassadnraPID | wc -l 74728 lsof |wc-l 5887913 # this is a very large number, don't know why. After OOM the open file numbers back to few hundreds (lsof | wc -l ). On Aug 10, 2015, at 9:59 AM, rock zhang r

Re: only grant select , but still can modify data

and DevCenter 1.4. What versions are you using? Did you check that the DevCenter connection properties are using the readonly account and that any existing connection was closed and re-opened? Did you get the expected result with cqlsh? dan On Mon, Aug 3, 2015 at 7:12 PM, rock zhang r...@alohar.com

only grant select , but still can modify data

Hi All, I want to create a readonly account, so i run the following command following: http://docs.datastax.com/en/cassandra/1.2/cassandra/security/security_config_native_authenticate_t.html CREATE USER readonly WITH PASSWORD '' ; GRANT SELECT ON ALL KEYSPACES TO readonly; Then I login

if seed is diff on diff nodes, any problem ?

Hi All, I have 6 node, most of them are using node1 as seed, but I just find out 2 nodes are using node3 as seed, but everything looks fine. Does that mean seed node does not have to be same on all nodes ? Thanks Rock

Re: After clean up, the whole system is down

I tried to restart , but always get out of memory error. Then I changed to use new seed node, then it works. I guess the possible reason is I run cleanup twice ? I need to run repair to fix some inconsistency issue, right ? Thanks Rock On Jul 25, 2015, at 8:39 AM, rock zhang r
