Subject java.lang.OutOfMemoryError: Map failed
Date Wed, 27 Oct 2010 17:43:52 GMT
While bootstrapping a new node, the existing node that is supposed to provide the data throws
an error, and the bootstrapping hangs. The log from the existing node is below. Both nodes
have little memory (only 2 Gig, windows machines). I used default configurations (Cassandra
0.7). Any suggestions how to fix this? Should I just add memory? Thanks Koert
