Pete Wyckoff commented on HADOOP-4619:
--------------------------------------
It is still an improvement and doubles the size of the files that can be
written from 2GB to 4GB on 32 bit machines.
It would be nice if we could easily detect overflow, but there is no OFF_MAX.
> hdfs_write infinite loop when dfs fails and cannot write files > 2 GB
