Attila Sasvari commented on CRUNCH-636:
---------------------------------------
[~joshwills] One of the new unittests
([initialReplicationFactorUsedFromFileSystem() |
https://github.com/apache/crunch/blob/master/crunch-core/src/test/java/org/apache/crunch/impl/mr/plan/JobPrototypeTest.java#L88]
) fails on CentOS 6.4 with java version "1.8.0_121" if you run all the
unittests together with {{mvn test}}. The issue is that if you create a new
Hadoop {{Configuration()}}, it checks for default files to load by default (see
[contructor |
https://github.com/apache/hadoop/blob/trunk/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/conf/Configuration.java#L714]).
Some tests earlier in crunch-core leaves something behind which confuses
{{initialReplicationFactorUsedFromFileSystem()}}. Please note I could not
see/reproduce this test failure on Mac OSX.
Does Crunch use amendment patches? Is it planned to use jenkins to catch issues
like this?
> Make replication factor for temporary files configurable

> As of now, Crunch does not allow having different replication factor for
> temporary files and non-temporary files (e.g. final output data of leaf
> nodes) at the same time. If a user has a large amount of data (say hundreds a
> of gigabytes) to process, they might want to have lower replication factor
> for large temporary files between Crunch jobs.
> We could make this configurable via a new setting (e.g.
> {{crunch.tmp.dir.replication}}).
