------------------------------------------
Summary: Open MapFile for append
Key: HADOOP-13725
URL: https://issues.apache.org/jira/browse/HADOOP-13725
Project: Hadoop Common
Issue Type: New Feature
Reporter: VITALIY SAVCHENKO
I think it possible to open MapFile for appending.
SequenceFile support it (Option SequenceFile.Writer.appendIfExists(true)
HADOOP-7139)
Now it almost working. But if use SequenceFile.Writer.appendIfExists(true)
MapFile.Writer - it not read last key and does not check new keys. That's why
MapFile can be corrupted.
