Create upgrade testing framework

[keith-turner]

See https://issues.apache.org/jira/browse/ACCUMULO-2145 for a description of work and prior work done.

This could use Uno. For testing apache/accumulo#1111 I wrote the following script that uses Uno.

#! /usr/bin/env bash

ACCUMULO_DIR=~/git/accumulo
UNO_DIR=~/git/uno
BULK=/tmp/upt

cd $ACCUMULO_DIR
git checkout 1.9
git clean -xfd
cd $UNO_DIR
./bin/uno fetch accumulo
./bin/uno setup accumulo
(
  eval "$(./bin/uno env)"

  hadoop fs -ls /accumulo/version


  hadoop fs -rmr "$BULK"
  hadoop fs -mkdir -p "$BULK/fail"
  accumulo org.apache.accumulo.test.TestIngest -i uno -u root -p secret --rfile $BULK/bulk/test --timestamp 1 --size 50 --random 56 --rows 200000 --start 200000 --cols 1

  accumulo org.apache.accumulo.test.TestIngest -i uno -u root -p secret --timestamp 1 --size 50 --random 56 --rows 200000 --start 0 --cols 1  --createTable --splits 10

  accumulo shell -u root -p secret <<EOF
   table test_ingest
   importdirectory $BULK/bulk $BULK/fail false
   createtable foo
   config -t foo -s table.compaction.major.ratio=2
   insert r1 f1 q1 v1
   flush -t foo -w
   scan -t accumulo.metadata -c file
   insert r1 f1 q2 v2
   insert r2 f1 q1 v3
EOF
)
pkill -9 -f accumulo\\.start
cd $ACCUMULO_DIR
git checkout accumulo-1111
git clean -xfd
cd $UNO_DIR
./bin/uno fetch accumulo
./bin/uno install accumulo --no-deps
./install/accumulo*/bin/accumulo-cluster start
(
  eval "$(./bin/uno env)"
  hadoop fs -ls /accumulo/version
  accumulo shell -u root -p secret <<EOF
    config -t foo -f table.compaction.major.ratio
    scan -t foo -np
    scan -t accumulo.metadata -c file
    compact -t foo -w
    scan -t foo -np
    scan -t accumulo.metadata -c file
EOF

  accumulo org.apache.accumulo.test.VerifyIngest --size 50 --timestamp 1 --random 56 --rows 400000 --start 0 --cols 1
