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]. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscribe@hadoop.apache.org For additional commands, e-mail: common-issues-help@hadoop.apache.org
