Problem regarding mysql cluster

rishabh pandey — Wed, 27 Oct 2010 12:49:32 GMT

Hi All,
I have implemented mysql cluster with configuration(1 management node, 4 data node, and 2 sql nodes).I stuck with a problem where my sql node is running but showing not connected on management client.
I have implemented it before with same configuration but now it is not working. Please help me out to resolve this. Thanks in advance.
