  • I have the correct four tasks to work with, unfortunately I don’t know how to save both sets of data so many tasks work as they should…

    A) Query the names of the clients that receive the least number of transactions, and return the names of the clients and the total number of transactions from .

    B) Associate clients and transactions using a broadcast (replicated) connection. Report: CustomerID, Name, Salary, NumOf Transactions, TotalSum, MinItems (where NumOfTransactions is the total number of phone transactions made by the visitor, TotalSum is the sum of the “TransTotal” battlefield for this customer, and MinItems is the number of Minimum Transaction Score, perfect by the respective customers.)

    C) Specify the number of customer country codes with more than 5000 if at least 2000.

    D) Suppose we really want to design a data analysis problem as follows: the age attribute is divided into six communities, namely [10, 20], [20, 30], [30, 40], [40, 50 ), [50 and 60], [60, 70]. Within each of the above age groups, a further subdivision is made according to “gender”, i.e. H each of the 6 age groups is then divided into fewer groups. Each group reports: age range, gender, MinTransTotal, MaxTransTotal, AvgTransTotal. Note. The bracket “[” means that the lower target of the range is included, where “)” means that the upper target of the range is excluded.

    Any ideas? I agree with you, are you misreading the entries causing the problem?

    I am trying to run the best basic pig_cassandra example including

    The number of rows in the wife and children column and I entered an error after:

    I tried several owners with the same result, but here it is

    Do you have any troubleshooting ideas? It’s obviously related to

    Cassandra then outputs the column family schema, so I guess

    This is a pig-style definition problem, but I didn’t believe it was

    Just for the record, Pete and I have been trying to resolve the issue via FB. I also experimented with Pig 0.9.1 after Cassandra 0.8.1. He will see if anything else happens.

    error 1031 incompatible schema

    rows = LOAD ‘cassandra://lala/FriendsAlreadyRanked’ USING CassandraStorage() (key like columns: bagT: tuple(name, value));

    Any troubleshooting ideas? This is obviously related to Cassandra as it pulls the definition of my column, family, so I’m assuming it’s a pig-like disease, but I didn’t understand everything she’s expecting (and any advice, just use the form above).

    For example, for pig_cassandra, I need to do the simplest thing – count

    I researched this after my script is still running

    error 1031 incompatible schema

    I’m at sea when I need to process real data. This is hunting as it could be

    getSchema() provides columns as inner joins to sets of tuples, each

    which contains 17 values. In fact, getNext() actually returns the inner bag

    I will archive each JIRA and do my best to help you create a fix so you do the right thing, but
