Subject [jira] [Commented] (CRUNCH-4) Create profiles for Crunch builds based on Hadoop 1.0 and Hadoop 2.0
Date Thu, 26 Jul 2012 05:52:33 GMT


Rahul Sharma commented on CRUNCH-4:

The hadoop 1.0.3 profile prints a few stack traces like ( output from WordCountHBaseIT test)

2940 [main] WARN  org.apache.hadoop.metrics2.util.MBeans  - Hadoop:service=DataNode,name=MetricsSystem,sub=Control MXBean already registered with name Hadoop:service=NameNode,name=MetricsSystem,sub=Control

But these all are warning and are listed in HBASE-4709 issue, which is yet to be fixed. I
think in future we need to spend some time in fixing them.

(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.)
