Hi! I've launched 4 instances of ElasticSearch (on one cluster - LocalCluster). 2 instances (test-1 and test-2) have configuration: http: enabled: true data: enabled: false And 2 other instances (test-3 and test-4) have configuration: http: enabled: false data: enabled: true But when I'm putting data to test-1 (using curl) I see that size of work directory work/LocalCluster is growing on test-1 and test-4, but in not growing on test-2 and test-3. Why is that? test-3 and test-4 are data nodes, test-1 and test-2 are non-data noded, but data seems to be stored in some other way. What is the explanation of that? Regards Szymon Gwóźdź ---

The configuration to enable or disable a data node is: node: data: false (the above disables a node from holding data). Try that and see if it works... cheers, shay.banon 2010/4/15 Szymon Gwóźdź [sz.gwozdz@gmail.com](mailto:sz.gwozdz@gmail.com) > Hi! > > I've launched 4 instances of Elasticsearch (on one cluster - LocalCluster). > 2 instances (test-1 and test-2) have configuration: > > http: > enabled: true > > data: > enabled: false > > And 2 other instances (test-3 and test-4) have configuration: > > http: > enabled: false > > data: > enabled: true > > But when I'm putting data to test-1 (using curl) I see that size of work > directory work/LocalCluster is growing on test-1 and test-4, but in not > growing on test-2 and test-3.
