[jira] [Updated] (PIG-1975) Need to provide backward compatibility
for legacy LoadCaster (without bytesToMap(bytes, fieldSchema))
[ https://issues.apache.org/jira/browse/PIG-1975?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Daniel Dai updated PIG-1975:
----------------------------
Attachment: PIG-1975-1.patch
No test added since it is impossible to make legacy LoadCaster compile in new code. Manual test success.

> Pig changed LoadCaster interface in 0.9 for typed map (PIG-1876). We change
> bytesToMap(byte[] b, ResourceFieldSchema fieldSchema)
> to
> bytesToMap(byte[] b)
> We should provide backward compatibility for old LoadCaster. If we don't find the new bytesToMap, we use the old bytesToMap to convert bytes to map with bytearray value. It is still wrong but at least matching the ability of old behavior.
