Sandbox 2.0 tutorial 1 error

  • #50475
    Malek Safa

    I have just installed Hortonworks Sandbox 2.0 on Oracle Virtual Box (Microsoft version) and while trying to complete the first tutorial (tutorial 1) i have faced the below error:

    ERROR org.apache.pig.PigServer – exception during parsing: Error during parsing. Could not resolve org.apache.hcatalog.pig.HCatLoader using imports: [, java.lang., org.apache.pig.builtin., org.apache.pig.impl.builtin.]

    below is my Pig script:

    a = LOAD ‘nyse_stocks’ USING org.apache.hcatalog.pig.HCatLoader();
    b = filter a by stock_symbol == ‘IBM’;
    c = group b all;
    d = foreach c generate AVG(b.stock_volume);
    dump d;

    what should i do to fix this issue?

    Thank you.

    i did find out many Resolutions like:

    1. Login to sandbox as root.
    2. vi /usr/bin/pig
    3. Replace the last line with the following line:
    exec /usr/lib/pig/bin/pig -useHCatalog “$@”

    however i was not able to login to sandbox as root using; username: root and password: hadoop, it didn’t work saying that username or password is wrong.

    You need to check the useHCatalog box at the bottom of the pig editor in hue for the script before running it.

    thank you Kevin, it is working now.
