Niels Basjes commented on AVRO-1862: ------------------------------------ If I create a tar archive and the compress it with gzip I get a name like {{example.tar.gz}}. If I gunzip that file I actually get a {{example.tar}} which is a tar archive. Avro files are Avro files. You cannot 'unavro' a {{example.gz.avro}} file and get a {{example.gz}} file. The other way around is also wrong using a name like {{example.avro.gz}} would lead to the expectation that it is a gzipped file and if you ungzip it you get a {{example.avro}}. Based on the explanation I interpret the reason behind this change as a workaround for a need in scripting to avoid certain situations. Alternative solution for the described use case: Run Camus in a script that after running the task simply renames the output file {{example.avro}} to {{example.camus.avro}} I see this as a problem that does not belong to the avro code base. So based on what I see here I think this should not be committed. > AvroOutputFormat saves compressed avrò files without respecting codec's > default extension > ----------------------------------------------------------------------------------------- > > Key: AVRO-1862 > URL: https://issues.apache.org/jira/browse/AVRO-1862 > Project: Avro > Issue Type: Improvement > Components: java > Affects Versions: 1.8.1 > Reporter: Piotr Wikieł > Priority: Minor > Labels: patch > Fix For: 1.8.3 > > Attachments: AVRO-1862-1.patch, AVRO-1862.patch > > > Common pattern in naming compressed files is giving them extension derived > from compression codec, for example: {{.gz}}, {{.zip}}, {{.bz2}}. > {{AvroOutputFormat}} currently does not respect this convention. > I've adapted some code from Hadoop's {{TextOutputFormat}} in > backward-compatible manner adding following {{JobConf}} property: > {{avro.mapred.output.extension.from-codec}} ({{boolean}}, default: {{false}}) > - when set to {{true}}, extension will be changed according to above rule. > EDIT: Please take a look at first comment for an update. {{.gz.avro}}, > {{.snappy.avro}} will be an extension of the file when above property will be > set to true. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
