I have mysql cluster setup with 2 hosts + 1 load balancer.
I am getting following error sometimes not always :
"Mysql::Error: Got error 157 'Unknown error code' from NDBCLUSTER: SELECT * FROM users ; "
I checked both mysql hosts. no host is down and mysql server is up on both hosts.
When i do ps ax. one host data node process shows:
23332 pts/2 S+ 0:20 ./xx 98
23333 pts/2 S+ 0:00 ./xx 98
Other host data node process shows:
1649 ? Ss 0:13 mysqlc/bin/ndbd -c localhost:1186
1650 ? Sl 122:55 mysqlc/bin/ndbd -c localhost:1186
I think this problem has something to do with data nodes. What does ./xx 98 mean ?
Anybody with his bright ideas ?
