Graham Gear created WHIRR-645:
---------------------------------
Summary: Race condition between collocated namenode and jobtracker
start/init services
Key: WHIRR-645
URL: https://issues.apache.org/jira/browse/WHIRR-645
Project: Whirr
Issue Type: Bug
Components: core
Affects Versions: 0.7.1
Reporter: Graham Gear
Priority: Minor
If the jobtracker role is defined before the namenode role on the same node (as
per majority of the examples), the jobtracker service will poll for namenode
and race the namenode HDFS dir config steps, often resulting in a failed write
of 'mapred.system.dir' and a dead jobtracker process.
