Dmitriy V. Ryaboy updated PIG-3480:
-----------------------------------
Attachment: PIG-3480.patch
Attaching a rough patch which replaces use of TFile with SequenceFile.
Next steps:
- evaluate effect on size of compressed data for TFile vs SeqFile when TFile
does work
- add tests, make TFile tests pass (in this file they fail, because of course
TFile is not being used)
- make SeqFile the default method, since it doesn't break
- allow TFile use by a switch, since current users may want to keep it. I would
prefer to not do that, but might if the first step shows significant
differences.
Thoughts?
Especially from folks using TFile-based compression in production ([~rohini]?)
