JVM Settings
If you want to provide JVM settings, like defining memory allocated to
FSCrawler, you can define a system property named FS_JAVA_OPTS:
FS_JAVA_OPTS="-Xmx521m -Xms521m" bin/fscrawler
You can also use the -D option to pass some jobs specific settings:
FS_JAVA_OPTS="-Dfs.url=/tmp/test" bin/fscrawler
