Hello
Can someone share some idea what the Hadoop source code of class org.apache.hadoop.io.compress.BlockDecompressorStream, method rawReadInt() is trying to do here?
The BlockDecompressorStream class is used for block-based decompression (e.g. snappy). Each chunk has a header indicating how many bytes it is. That header is obtained by the rawReadInt method so it is expected to return a non-negative value (since you can't have a negative length).
