Hello, Did you mean /var/run/hadoop/hdfs/namenode/formatted?
I cannot restart namenode from the UI. HDFS icon keeps on blinking but the Start and Stop buttons are disabled. Thanks. Dustine On 3/14/2013 3:17 PM, Mahadev Konar wrote:
Hi Dustine, Are you installing on a cluster that was already installed via Ambari? If yes, then remove this directory in /var/run/hadoop/hdfs/formatted and restart namenode from the the UI and it should work. If not then its a bug and please create jira nad attach logs for Namenode/amabari agent and server. thanks mahadev On Thu, Mar 14, 2013 at 12:13 AM, Dustine Rene Bernasor <[email protected]> wrote:Hello, I was installing Ambari 1.2.1.
