By the way, I don't think that it is a good idea to configure the same data region using different values of the `enablePersistence` flag. I hope that such a check will be added in the near future. https://issues.apache.org/jira/browse/IGNITE-8951 Thanks, S. ср, 1 авг. 2018 г. в 19:51, wangsan <wqp1...@gmail.com>: > Thank you for your answer, > Maybe I use region config the wrong way. > There are two apps(more apps with different roles) with different ignite > configs, > first App > :set default region with persistence enable > :set cache a,with nodefilter in first apps,default region > second app > :set default region with persistence disable > :just access cache a with query > > start first app instance 1,second app instance 2,and first app instance 3. > then close 1, > then restart 1, the deadlock will happes > > fyi, I use ignitelock in first apps when process ignite discovery event > such > as join event. when a new node join, apps 1,3 will receive join message by > local event listener, but I just want one node to process the message, so i > use it like this: > > if (globalLock.tryLock()) { > LOGGER.info("------ hold global lock "); > try { > switch (event.type()) { > case EventType.EVT_NODE_JOINED: > joinListener.onMessage(clusterNode); > break; > case EventType.EVT_NODE_FAILED: > case EventType.EVT_NODE_LEFT: > leftListener.onMessage(clusterNode); > break; > default: > LOGGER.info("ignore discovery event: {}", > event); > break; > } > } finally { > LOGGER.debug("------ process event done "); > // don't unlock until node left > // globalLock.unlock(); > } > } > > the node which hold the globalLock will never unlock unless it left, Is it > the right way with lock > > > > > -- > Sent from: http://apache-ignite-users.70518.x6.nabble.com/ >
