Subject Re: After setting streamer and ignite,getting NULL
Date Sat, 26 Sep 2015 06:29:21 GMT
Gian,

I have followed instructions given by you. I instantiate IgniteDateStreamer
and ignite in prepare() method of bolt. but getting "*Cache doesn't exist*".

Code snippet from stormStreamer class in prepare() method

StormStreamer<String, String, String> stormStreamer = null;

Ignite ignite = Ignition.start();

System.out.println(" ignite ====== "+ignite.toString());

try(IgniteDataStreamer<String, String> stmr = ignite.dataStreamer("cache-0")) {

    stormStreamer = new StormStreamer<>();

    IgniteCache<String, String> cache = ignite.cache("cache-0");

    stmr.allowOverwrite(true);

    /*  Set ignite instance */
    stormStreamer.setIgnite(ignite);

    /* Set streamer instance */
    stormStreamer.setStreamer(stmr);

    /* set thread count */
    setThreads(5);

}
