Enrico Olivelli commented on IGNITE-1564:
-----------------------------------------
I found a workaround.
My previuos code was like this:
{code}
Ignite ignite = ....
set forceservermode = true
IgniteCache cache = ignite.getOrCreateNearCache(....);
while (true) {
try {
cache.get(...)
} catch (Exception tryagain) {
tryagain.printStackTrace();
}
Thread.sleep(xxxx);
}
{code}
New code which recovers from servers shutdown:
{code}
Ignite ignite = ....
set forceservermode = false
whiel (true) {
try {
IgniteCache cache = ignite.getOrCreateNearCache(....);
cache.get(...)
} catch (Exception tryagain) {
tryagain.printStackTrace();
}
Thread.sleep(xxxx);
}
{code}
