PHOENIX-3240 Create phoenix-$VERSION-pig shaded jar
Running inside of Pig's environment creates some issues where Pig is already
providing some versions of dependencies (e.g. joda-time). Create a custom
JAR specifically to be used with Pig.
Testing approach:
1. `create table foobar(a varchar, b date not null, constraint pk primary
key (a, b));`
2. `cd /usr/local/lib/pig-0.16.0`
3. `PIG_HOME=$(pwd)
PIG_CLASSPATH=/usr/local/lib/phoenix/phoenix-4.9.0-HBase-1.2-SNAPSHOT-pig.jar
./bin/pig` (or alternatively, `register
/usr/local/lib/phoenix/phoenix-4.9.0-HBase-1.2-SNAPSHOT-pig.jar` in the pig
interpreter)
4. Create a two-column CSV file in HDFS (e.g. `a1,2016-10-10 17:05:00`)
5. `A = load 'times' using PigStorage(',') as (a:chararray, b:datetime);`
6. `STORE A into 'hbase://FOOBAR' using
org.apache.phoenix.pig.PhoenixHBaseStorage('localhost:2181:/hbase-1.2','-batchSize
100');`
7. `select * from FOOBAR;`
