PigStorage
---------------------------------------------------------------------------------------
Key: PIG-1271
URL: https://issues.apache.org/jira/browse/PIG-1271
Project: Pig
Issue Type: Bug
Affects Versions: 0.7.0
Reporter: Daniel Dai
Assignee: Daniel Dai
With [PIG-613|https://issues.apache.org/jira/browse/PIG-613], we are able to
load txt files containing complex data type (map/bag/tuple) according to
schema. However, the format of complex data field is very strict. User have to
use pre-determined special characters to mark the beginning and end of each
field, and those special characters can not be used in the content. The goals
of this issue are:
1. Provide a way for user to escape special characters
2. Make it easy for users to customize Utf8StorageConverter when they have
their own data format
