问题 I am trying to overload the << operator. I have successfully overload the other operators but this last one is giving me trouble. Maybe it just needs a new set of eyes. I have a feeling it is all being caused by a const qualifier. Where I need the operator to work. for(UINT i = 0; i < setVector.size(); ++i) { outStream << "SET " << i << setVector[i] << endl; } where setVector is a vector of type Set. Set is a vector of int . This is my operators.cpp /******************************************

问题 When I import data to hive using sqoop bydefault it creates file name as part-m-0000, part-m-0001 etc on HDFS. Is it possible to rename these files? If i wish to give some meaningfull name like suffxing file name with date to indicate load how can I do it? Please suggest 回答1: You can't do it with sqoop directly, but you can rename them in HDFS after sqoop is done importing: today=`date +%Y-%m-%d` files=$(hadoop fs -ls /path-to-files | awk '{print $8}') for f in $files; do hadoop fs -mv $f $f

问题 I was hoping somebody could help, I'm new to scala and I'm having some issues writing my output to a text file. I have a data table and I've written some code to read it in one line at a time, do what I want it to do, and now I need it to write that line to a text file. So for example, I have the following table of data type Name, Date, goX, goY, stopX, stopY 1, 12/01/01, 1166, 2299, 3300, 4477 My code, takes the first characters of goX and goY and creates a new number, in this instance 1.2
