big-data-code's Issues

Batch Layer Code Fails on Hadoop 2.7.0, Linux Ubuntu Trusty 14-04

Am facing issues in setting up Batch Layer successfully.

I introduced a main function in BatchWorkflow.java of manning.batchlayer package as follows:

{
    initTestData();
    batchWorkflow();
}

When I run this under hadoop (with 1 namenode and 2 datanodes), it fails at:

batchWorkflow()->ingest()->appendNewDataToMasterDataPail()->shred()->Api.execute()

with following output + exception:

Any input to fix the issue will be appreciated. Thanks.

See attached code pls, When lastTime var is not null?

public static class AnalyzeVisits extends CascalogBuffer {
    private static final int VISIT_LENGTH_SECS = 60 * 15;

    public void operate(FlowProcess process, BufferCall call) {
        Iterator<TupleEntry> it = call.getArgumentsIterator();
        int bounces = 0;
        int visits = 0;
       Integer lastTime = null;                       <- lastTime initialized
        int numInCurrVisit = 0;
        while(it.hasNext()) {
            TupleEntry tuple = it.next();
            int timeSecs = tuple.getInteger(0);
            if(lastTime == null ||
                    (timeSecs - lastTime) > VISIT_LENGTH_SECS) {    <-- ??? when lastTime updated
                visits++;
                if(numInCurrVisit == 1) {
                    bounces++;
                }
                numInCurrVisit = 0;
            }
            numInCurrVisit++;
        }
        if(numInCurrVisit==1) {
            bounces++;
        }
        call.getOutputCollector().add(new Tuple(visits, bounces));
    }
}

Compile Errors (Ubuntu 14.04)?

Java noob here. Trying to compile and use Pail examples from Big Data book on Ubuntu 14.04. Below is the full output. Any and all help greatly appreciated! I'll continue to try and figure out. @handdola @nagarajanchinnasamy - kindly lend a hand? Cheers.
