Subject [jira] [Commented] (HADOOP-13340) Compress Hadoop Archive output
Date Thu, 11 Jan 2018 17:55:00 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-13340?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16322663#comment-16322663

Ruslan Dautkhanov commented on HADOOP-13340:
--------------------------------------------

[~jlowe] A workaround might be to compress only files for which compression makes sense? For
example it doesn't make a lot of sense to compress tiny files.
It may make sense to compress when files are over a few Kb. Not sure if a hard-coded source
file size would do. If it's over a threshold, that one file will be compressed.

> Why Hadoop Archive tool cannot compress output like other map-reduce job? 
> I used some options like -D mapreduce.output.fileoutputformat.compress=true -D mapreduce.output.fileoutputformat.compress.codec=org.apache.hadoop.io.compress.GzipCodec
but it's not work. Did I wrong somewhere?
> If not, please support option for compress output of Hadoop Archive tool, it's very neccessary
for data retention for everyone (small files problem and compress data).
