Example 1 with JdbcClient

use of org.apache.storm.jdbc.common.JdbcClient in project storm by apache.

the class AbstractUserTopology method execute.

public void execute(String[] args) throws Exception {
    if (args.length != 4 && args.length != 5) {
        System.out.println("Usage: " + this.getClass().getSimpleName() + " <dataSourceClassName> <dataSource.url> " + "<user> <password> [topology name]");

    }
    this.jdbcClient = new JdbcClient(options.connectionProvider, options.queryTimeoutSecs);
}

Example 3 with JdbcClient
