Hbase:Need suitable jar files for cloudera-quickstart-vm-5.4.2-0 - hadoop

Question

I am trying to load data from flat file to Hbase through API.But I am getting following error

table.put(p);
line = br.readLine();
}
br.close();
table.close();
}
else
System.out.println("Table Already exists.
Please enter another table name");
}
else
System.out.println("Please Enter the table
name through command line");
}
}
Please let me know whether we need to add any suitable jars ..I am using cloudera cloudera-quickstart-vm-5.4.2-0
Thanks,

Answer 1

If you read the error, it says that the Integer.parseInt method raised a NumberFormatException. This means that you attempted to convert a String of invalid format into an Integer. In your code, you call that method in this line:
Bytes.toBytes(Integer.parseInt(tokens.nextToken())));
You need look at the tokens you're passing into this method via tokens.nextToken() and ensure that each can be converted to an Integer.

Answer 2

I think the problem is with the cloudera jar versions used. Please check on it, that should work.
