[jira] [Updated] (CRUNCH-4) Create profiles for Crunch builds based
on Hadoop 1.0 and Hadoop 2.0
[ https://issues.apache.org/jira/browse/CRUNCH-4?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Rahul Sharma updated CRUNCH-4:
------------------------------
Attachment: 0001-Created-profiles-for-CDH3-hbase-.90.6-and-hadoop2-hb.patch
I created profiles for CDH3/hbase .90 and hadoop2/hbase .92 . Also tests/srcs were modified for the same. By default CDH3 profile gets built. The other can be invoked by setting property crunch.platform=2
In hadoop 2 the Aggregate API returned output in reverse order. Also the Distributed Cache behavior was a bit different.
A hadoop2 run shows a bunch of deprecated warning eg:
42334 [Thread-288] WARN org.apache.hadoop.conf.Configuration - mapred.cache.files is deprecated. Instead, use mapreduce.job.cache.files
42336 [Thread-288] WARN org.apache.hadoop.conf.Configuration - mapred.reduce.tasks is deprecated. Instead, use mapreduce.job.reduces
42337 [Thread-288] WARN org.apache.hadoop.conf.Configuration - mapred.output.key.comparator.class is deprecated. Instead, use mapreduce.job.output.key.comparator.class
42338 [Thread-288] WARN org.apache.hadoop.conf.Configuration - mapred.mapoutput.value.class is deprecated. Instead, use mapreduce.map.output.value.class
42340 [Thread-288] WARN org.apache.hadoop.conf.Configuration - mapreduce.map.class is deprecated. Instead, use mapreduce.job.map.class
42342 [Thread-288] WARN org.apache.hadoop.conf.Configuration - mapred.job.name is deprecated. Instead, use mapreduce.job.name
42344 [Thread-288] WARN org.apache.hadoop.conf.Configuration - mapreduce.reduce.class is deprecated. Instead, use mapreduce.job.reduce.class
Should we try to fix them ?
I did not made a profile for hadoop1 as a version of the same could not be found in Cloudera repository.

> We need to create two Maven build profiles for Crunch, one that depends on Hadoop 1.0 (probably 1.0.3 for Hadoop and 0.90.5 for HBase) and Hadoop 2.0 (2.0.0-alpha for Hadoop and a stable 0.92.x for HBase.)
