Hi,
we just upgraded a cluster from CDH 4.0.1 to 4.1.2 on a number of nodes
running on Ubuntu 12.04 (Precise).
We first upgraded Cloudera Manager (now 4.1.0), then ran apt-get
dist-upgrade on all nodes, started CM, checked and updated the
configuration and attempted to start the cluster.
However, the HDFS NameNode fails to start with the exception appended below.
There is sufficient space on all partitions. We do not bind against
wildcard addresses (at least not yet).
Any ideas? Stacktrace follows.
Cheers,
Martin
