Start a single instance Ignite server node locally, then connect this Ignite
cluster and run the previous test code, run successfully; then connect the
original distributed three-node Ignite cluster again, the test code also
runs successfully, what is the reason? Will the Ignite client buffer some
information locally?View the service node logs of the distributed three-node
Ignite cluster and report no related errors.The test code that was not
displayed in the previous reply is as follows: try {
Ignition.setClientMode(true); IgniteConfiguration cfg = new
IgniteConfiguration();
cfg.setIgniteInstanceName("IgniteTest-Client");
TcpDiscoveryVmIpFinder ipFinder = new TcpDiscoveryVmIpFinder();
ipFinder.setAddresses(Arrays.asList("192.168.0.219", "192.168.0.220",
"192.168.0.221")); TcpDiscoverySpi spi = new
TcpDiscoverySpi();
spi.setIpFinder(ipFinder); cfg.setDiscoverySpi(spi);
try (Ignite ignite
= Ignition.start(cfg)) {
Class.forName("org.apache.ignite.IgniteJdbcThinDriver");
try (Connection
conn = DriverManager.getConnection("jdbc:ignite:thin://127.0.0.1/"))
{
try (Statement stmt = conn.createStatement())
{
stmt.executeUpdate("DROP TABLE IF EXISTS City");
stmt.executeUpdate("DROP TABLE IF EXISTS Person");
// Create table
based on REPLICATED template.
stmt.executeUpdate("CREATE TABLE IF NOT
EXISTS City(id LONG PRIMARY KEY, name VARCHAR) "
+ "WITH
\"template=replicated\""); //
Create table based on PARTITIONED
template with one backup.
stmt.executeUpdate("CREATE TABLE IF NOT
EXISTS Person ( id LONG, name VARCHAR, city_id LONG, PRIMARY KEY (id,
city_id)) " + "WITH
\"backups=1, affinityKey=city_id\"");
//
Create an index on the City table.
stmt.executeUpdate("CREATE INDEX IF
NOT EXISTS idx_city_name ON City (name)");
// Create an index on the
Person table.
stmt.executeUpdate("CREATE INDEX IF NOT EXISTS
idx_person_name ON Person (name)"); }
} } }
catch (Exception ex)
{ ex.printStackTrace(); }
