Hi all, I am running a Pig Script which is running fine for small data. But when I scale the data, I am getting the following error at my map stage. Please refer to the map logs as below. My Pig script is doing a group by first, followed by a join on the grouped data. Any clues to understand

Re: java.lang.OutOfMemoryError: Java heap space

Problems building hadoop 2.2.0 from source

Hi, I am a complete beginner to Hadoop, trying to build 2.2.0 from source on a Macbook Pro running OS X Mavericks. I am following the 'instructions' at http://hadoop.apache.org/docs/current/hadoop-project-dist/hadoop-common/SingleCluster.html such as they are. I get the following test failure:

There isn't System.exit call in TestMRJobsWithHistoryService.java What did hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client-jobclient/target/surefire-reports/org.apache.hadoop.mapreduce.v2.TestMRJobsWithHistoryService.txt say ? Cheers On Thu, Feb 6, 2014 at 4:41 PM,

Re: Problems building hadoop 2.2.0 from source

I checked out source code from http://svn.apache.org/repos/asf/hadoop/common/branches/branch-2.3 and it builds. From TestMRJobsWithHistoryService.txt, the test passed. What led to this test being singled out among the 454 tests ? Thanks On Thu, Feb 6, 2014 at 7:26 PM, Christopher Thomas

Re: Problems building hadoop 2.2.0 from source

I included the last part of hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client- jobclient/target/surefire-reports/org.apache.hadoop.mapreduce.v2. TestMRJobsWithHistoryService.txt in the second half of my initial posting, calling it the output from

Re: Problems building hadoop 2.2.0 from source

I guess the ERROR lines in hadoop-mapreduce-project/hadoop-mapreduce-client/hadoop-mapreduce-client- jobclient/target/surefire-reports/org.apache.hadoop.mapreduce.v2. TestMRJobsWithHistoryService-output.txt led me to believe that the problem was with TestMRJobsWithHistoryService. If that's not
