Adam Szita commented on PIG-5159:
---------------------------------
Looks like the old version of jline took care of history persistence itself
(after each line being read from console):
https://github.com/jline/jline/blob/master/src/main/java/jline/History.java#L102
The new version doesn't, we have to call flush() explicitly.
[~daijy], can you please take a look at [^PIG-5159.0.patch]
> Fix Pig not saving grunt history

> After quitting Pig (grunt) and restarting it I cannot see my last Pig latin
> statements.
> Cause is that pig history file (~/.pig_history) is only being read on Pig
> startup, but is not being written. This can be traced back to the recent
> jline upgrade PIG-3851.
