Rohini Palaniswamy reopened PIG-3615:
-------------------------------------
Based on https://github.com/rails/rails/issues/6033, I would say that this
should not be the default behavior and instead an option. Can you put a new
patch to revert to the old behavior by default and add a new overloaded
constructor to JSonLoader and JsonStorer that takes options and use the
--encode-bigdecimal-as-string switch to determine to go with the new behaviour.
You can refer to PigStorage,HBaseStorage etc for specifying options in
constructor.
> Update the way that JsonLoader/JsonStorage deal with BigDecimal

> It's a common (and good) convention to quote fixed point numbers when storing
> them as json. The reason being that majority of json libraries will
> implicitly load any number value as a floating point number and if you care
> about data integrity this will make you very sad.
> This update makes JsonLoader able to load BigDecimal values from quoted
> values (the old jackson library that we're using doesn't support this through
> the current approach) as well as making JsonStorage store BigDecimal values
> as quoted strings.
