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.
