Hazem Mahmoud commented on MAPREDUCE-6900:
------------------------------------------
One idea is to use mapreduce.client.submit.file.replication, which should allow
us to pass in as an argument to the terasort cmd
> Terasort replication factor hard-coded for partition file (partFile)

> Key: MAPREDUCE-6900
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-6900
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Reporter: Hazem Mahmoud
> Priority: Minor
>
> When running terasort on a cluster with less than 10 nodes, I get the
> following:
> 17/06/12 11:18:21 ERROR terasort.TeraSort: Requested replication factor of 10
> exceeds maximum of 4 for /tmp/hive/tera-out/_partition.lst from 172.31.114.66
> There is no way to set this, as it is hard-coded here:
> src/main/java/org/apache/hadoop/examples/terasort/TeraInputFormat.java
> {code:java}
> DataOutputStream writer = outFs.create(partFile, true, 64*1024, (short)
> 10,
>
> outFs.getDefaultBlockSize(partFile));
> {code}
> Had to modify TeraInputFormat.java and rebuild to get it to work. This should
> be configurable.
