----------------------------------------
Summary: 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.
