> Project: Hadoop Common
> Issue Type: Bug
> Components: io
> Affects Versions: 1.0.3, 2.0.0-alpha

> ResetableGzipOutputStream creates invalid gzip files when finish() and
> resetState() are used. The issue is that finish() flushes the compressor
> buffer and writes the gzip CRC32 + data length trailer. After that,
> resetState() does not repeat the gzip header, but simply starts writing more
> deflate-compressed data. The resultant files are not readable by the Linux
> "gunzip" tool. ResetableGzipOutputStream should write valid multi-member gzip
> files.
> The gzip format is specified in [RFC
> 1952|https://tools.ietf.org/html/rfc1952].
