Description:
The restservice.tar.gz is used to query data in NOSQL data sources, such as MongoDB, CouchDB and Hadoop
parquet. For Db2 v111m3fp3 or later on linuxamd64 platform you can just download the restservice.tar.gz 
and unzip it into the ~/sqllib/federaion directory, for Db2 v111m4fp4 on aix platform you need a special
Db2 build before you download the file.

Usage:
1 Download the restservice.tar.gz 
2 Unzip it into Instance_path/sqllib/federation, for example,

for linuxamd64
$ tar -zxvf restservice.tar.gz
for aix64
$ gunzip -c restservice.tar.gz | tar -xvf -

$ ls /home/db2inst1/sqllib/federation
jdbc         netezza      odbc         restservice
