# This script is used to generate the hadoop-*-api.report.json files in the
# test/resources directory.  To use it, you will first need to download an
# Apache binary distribution of Hadoop and set APACHE_HADOOP_DIR to the
# directory where you untar that distribution.  You will then need to set
# BIGTTOP_HOME to the directory where your bigtop source is located.  Then
# run this script for each of the jars you want to generate a report for.
# The arguments passed to this script should be -p <outputdir> -j <jarfile>
# where outputdir is the directory you'd like to write the report to and
# jarfile is the full path of the jar to generate the report for.  Reports
# should be generated for the following jars: hadoop-common, hadoop-hdfs,
# hadoop-yarn-common, hadoop-yarn-client, hadoop-yarn-api, and
# hadoop-mapreduce-client-core
#
# Example usage:
# export APACHE_HADOOP_DIR=/tmp/hadoop-2.7.3
# export BIGTOP_HOME=/home/me/git/bigtop
# $BIGTOP_HOME/bigtop-tests/spec-tests/runtime/src/main/resources/api-examiner.sh -j $HADOOP_HOME/share/hadoop/common/hadoop-common-2.7.3.jar -p $BIGTOP_HOME/bigtop-tests/spec-tests/runtime/src/test/resources
#
# The resulting reports should be committed to git.  This script only needs
# to be run once per ODPi release.
