Description

Joining my UTF8 patch HADOOP-1283 with synchronization changes introduced by HADOOP-1269
I missed to remove synchronization modifiers in the following three methods:
startFile()
getAdditionalBlock()
allocateBlock()

Fine grained locking does not work if the first two methods are synchronized.
This is the patch that removes them.
