I have been banging my head against this and still can not seem to find an answer:
2014-11-03 17:11:09,122 – Error while executing command ‘start':
Fail: Execution of ‘ulimit -c unlimited; export HADOOP_LIBEXEC_DIR=/usr/lib/hadoop/libexec && /usr/lib/hadoop/sbin/hadoop-daemon.sh –config /etc/hadoop/conf start datanode’ returned 1. starting datanode, logging to /var/log/hadoop/hdfs/hadoop-hdfs-datanode-igor1.attlocal.net.out
Core-site.xml
hdfs-site.xml
Both look fine.
Any suggestions?
