Hi list,
Can someone please tell me why this code prints
1242487951 WARN usage_report :
(/Users/m/hypertable/src/cc/Hyperspace/ClientConnectionHandler.h:65)
Connection attempt to Hyperspace.Master at 127.0.0.1:38040 - COMM
already connected
after wait_for_connection is called and hangs on open() call ?
int main(int argc, char *argv[])
{
ClientPtr client = new Client(System::locate_install_dir(argv[0]));
HyperspaceCallback callback;
Hyperspace::SessionPtr session(new
Hyperspace::Session(Comm::instance(), properties, &callback));
session->wait_for_connection(2000);
vector<String> tables;
vector<String>::const_iterator it;
client->get_tables(tables);
for (it = tables.begin(); it != tables.end(); ++it) {
TablePtr t = client->open_table(*it);
string table_file = "/hypertable/tables/"; table_file += *it;
HandleCallbackPtr null_callback;
uint64_t handle = session->open(table_file, OPEN_FLAG_WRITE |
OPEN_FLAG_LOCK_EXCLUSIVE, null_callback);
session->close(handle);
}
}
?

it suggests that the session never enters SAFE state? What's wrong
with my code above?
