> According to the tutorial
> http://oodt.apache.org/components/maven/curator/user/basic.html, I added a
> new JSON product type to my file manager. However, if I run the query_tool
> script before any json files ingested, it will raise some errors, as shown
> here:
> $ ./query_tool --url http://localhost:9000 --sql -query "SELECT * FROM JSON"
