can we deploy the HttpFS role on more than one node? is it best practice?
we had a problem with one of the namenodes (on node02) in our cluster and it was down for almost 20 hours.
once node02 was up, the active namenode ,on node01, started to alert that its not syncronized
after restart of the namenode on node02 the alert stopped
now active namenode is on node01
standby namenode is on node02
we can see that new logs are created on opt/hadoop/dfs/nn/current on the actine namenode on node01
but no new files . on the standby namenode no node02 - is it OK ??
