It¹s possible something was running. I only did an accumulo/stop-all.sh and sometimes i¹ve noticed i have to go to each node to stop-here.sh.
[root@txoig-hdfs02:accumulo-1.5.0]$ ls /hadoop/hdfs drwxr-xr-x. 5 hdfs 4.0K Jan 26 16:10 namesecondary [root@txoig-hdfs01:~]$ ls /hadoop/hdfs/ drwxr-xr-x. 5 hdfs 4.0K Jan 26 16:10 namenode [root@txoig-hdfs03:~]$ ls /hadoop/hdfs drwxr-xr-x. 4 root 4.0K Jan 26 16:13 namenode # this is weird. Wasn¹t expecting a second name node. We aren¹t doing HA. But shutting down all accumulo and hdfs and then doing the same procedure, i still see [root@txoig-hdfs01:~]$ hadoop fs -ls / Found 5 items drwxr-xr-x - hdfs hdfs 0 2014-01-26 13:36 /accumulo drwxr-xr-x - hdfs hdfs 0 2013-12-19 18:17 /apps drwx------ - mapred hdfs 0 2014-01-26 14:32 /mapred drwxrwxrwx - hdfs hdfs 0 2014-01-26 14:56 /tmp drwxr-xr-x - hdfs hdfs 0 2013-12-30 15:11 /user On 1/26/14, 4:16 PM, "Christopher" <[email protected]> wrote: >Was any part of Hadoop or Accumulo still running when you did this? >Are you sure you deleted the right HDFS data directory referenced in >your Hadoop configuration? > >-- >Christopher L Tubbs II >http://gravatar.com/ctubbsii > > >On Sun, Jan 26, 2014 at 4:45 PM, Kesten Broughton <[email protected]> >wrote: >>> >>>We did experiments using the root dir for both name nodes and datanodes. >>>Now we want to wipe out the old hdfs cluster, keeping the name node at >>>/hadoop/hdfs/namenode but moving the datanode fs to /dev/sdb etc. >> >> After removing /hadoop/hdfs/data on each of the datanode machines and >>doing >> hadoop namenode -format >> >> I still see /accumulo on >> hadoop fs -ls / >> >> I was expecting it to be gone. >> >> kesten >>
