Hi Harsh, I have made my dfs.namenode.name.dir point to a subdirectory of my home, and I don't see this issue again. So, is this a bug that we need to log into JIRA? Thanks, Kishore On Tue, Jul 16, 2013 at 6:39 AM, Harsh J ha...@cloudera.com wrote: 2013-07-12 11:04:26,002 WARN

Yeah I believe your /tmp was probably misbehaving somehow (running out of space or otherwise). You could log a JIRA for the null seen in the log though, it shouldn't have done that and should've shown the real mount point. On Fri, Jul 19, 2013 at 8:47 PM, Azuryy Yu azury...@gmail.com wrote: this

Yes Harsh, I haven't set dfs.namenode.name.dir anywhere in config files. My name node has again gone into safe mode today while it was idle. I shall try setting this value to something other than /tmp On Tue, Jul 16, 2013 at 6:39 AM, Harsh J ha...@cloudera.com wrote: 2013-07-12 11:04:26,002

Hi, I am doing no activity on my single node cluster which is using 2.1.0-beta, and still observed that it has gone to safe mode by itself after a while. I was looking at the name node log and see many of these kinds of entries.. Can anything be interpreted from these? 2013-07-12 09:06:11,256
