Tom White reopened HADOOP-6663: ------------------------------- Re-opening as there was a compilation problem. > BlockDecompressorStream get EOF exception when decompressing the file > compressed from empty file > ------------------------------------------------------------------------------------------------ > > Key: HADOOP-6663 > URL: https://issues.apache.org/jira/browse/HADOOP-6663 > Project: Hadoop Common > Issue Type: Bug > Components: io > Affects Versions: 0.20.2 > Reporter: Kang Xiao > Assignee: Kang Xiao > Fix For: 0.22.0 > > Attachments: BlockDecompressorStream.java.patch, > BlockDecompressorStream.java.patch, BlockDecompressorStream.patch, > HADOOP-6663.patch > > > An empty file can be compressed using BlockDecompressorStream, which is for > block-based compressiong algorithm such as LZO.
