Upgrade from 2.2.0.0 to 3.3.0.0
-------------------------------
1. Stop 2.2.0.0 cluster on master node
   $ hawq stop cluster -a

2. Backup 2.2.0.0 configuration on each node
   $ cp -rf $GPHOME/etc ~/

3. Backup 2.2.0.0 yum repository on each node

4. Setup 3.0.0.0 yum repository on each node

5. Install 3.0.0.0 rpm package on each node
   $ sudo yum remove -y hawq

   $ cp -rf ~/etc/* $GPHOME/etc/

7. Install ORC format

   1) Configure the cluster to upgrade mode
   $ hawq start cluster 
   $ hawq config -c upgrade_mode -v on --skipvalidation
   $ hawq restart cluster -a  

   2) Install ORC format in pg_catalog.pg_proc table in template1 on master node
      Please find $hawq_master_address_port in $GPHOME/etc/hawq-site.xml
   $ PGOPTIONS='-c gp_session_role=utility' psql -a -p $hawq_master_address_port -d template1 -f $GPHOME/share/postgresql/orc_install.sql > orc_install.out 2>&1

   3) Install ORC format in pg_catalog.pg_proc table in template1 on segment node
      Please find $hawq_segment_address_port in $GPHOME/etc/hawq-site.xml
   $ PGOPTIONS='-c gp_session_role=utility' psql -a -p $hawq_segment_address_port -d template1 -f $GPHOME/share/postgresql/orc_install.sql > orc_install.out 2>&1

   4) Configure the cluster to normal mode
   $ hawq config -c upgrade_mode -v off --skipvalidation
   $ hawq restart cluster -a 

   5) Get user database name on master node
   $ psql -a -d template1 -c "select datname from pg_database where datname not in ('hcatalog', 'template0', 'template1') order by datname;"

   6) Install ORC format in pg_catalog.pg_proc table in each user database on master node
   $ psql -a -d $user_database_name -f $GPHOME/share/postgresql/orc_install.sql > orc_install.out 2>&1

   7) Restart cluster on master node
   $ hawq restart cluster -a

8. Uninstall ORC format if necessary
   Refer to installation of ORC format while use /user/local/hawq/share/postgresql/orc_uninstall.sql instead of /user/local/hawq/share/postgresql/orc_install.sql
