Re: Does event listener keep the order of events as they occur on the cluster?

Re: Nodes distribution/nodes in parallel on one host using Yarn

Re: 3rd party persistence with Hive

Thanks Ivan for confirming my suspicions around the query support for Hive. I did attempt the SQLServerDialect as well but had the same results. I did get a success message for the load but no data was actually loaded into the cache so it appears that was a false positive. -- Sent from: http:/
