Sandbox 2.3 – Could not resolve org.apache.hive.hcatalog.pig.HCatLoader

I am doing the tutorial labs and I’m having a problem with Pig (Lab 3: Pig – Risk Factor):

http://hortonworks.com/hadoop-tutorial/hello-world-an-introduction-to-hadoop-hcatalog-hive-and-pig/#section_9

I am running “Hortonworks Sandbox with HDP 2.3″ using VirtualBox 4.3.30 on Ubuntu 14.04 LTS 64bit host.

When executing the following pig script:

a = LOAD ‘geolocation’ using org.apache.hive.hcatalog.pig.HCatLoader();

b = filter a by event != ‘normal';

c = foreach b generate driverid, event, (int) ‘1’ as occurance;

d = group c by driverid;

e = foreach d generate group as driverid, SUM(c.occurance) as t_occ;

g = LOAD ‘drivermileage’ using org.apache.hive.hcatalog.pig.HCatLoader();

h = join e by driverid, g by driverid;

final_data = foreach h generate $0 as driverid, $1 as events, $3 as totmiles, (float) $3/$1 as riskfactor;

store final_data into ‘riskfactor’ using org.apache.hive.hcatalog.pig.HCatStorer();

I get the following error:

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

Failed to parse: Pig script failed to parse:

<file script.pig, line 1, column 29> pig script failed to validate: org.apache.pig.backend.executionengine.ExecException: ERROR 1070: Could not resolve org.apache.hive.hcatalog.pig.HCatLoader using imports: [, java.lang., org.apache.pig.builtin., org.apache.pig.impl.builtin.]

I’ve seen some related postings but all with much older versions of the Sandbox. I’ve the following with no success:

1. Login to sandbox as root.

2. Edit file /usr/bin/pig

3. Replace the last line with the following line:

exec /usr/lib/pig/bin/pig -useHCatalog “$@”

This may no longer apply as was posted in 2013.
