The other things to check would be ability to ping from slave nodes,
correct fqdn in the slave nodes hadoop-site.xml file, correct dns setup
for the master.

If the hosts file on the namenode is not setup correctly it could be
listening only on localhost. Make sure your /etc/hosts file looks
something like this:
127.0.0.1 localhost, localhost.localdomain
x.x.x.x yourcomputer.domain.tld

In theory I have a cluster with 4 nodes. When running something like
bin/slaves.sh uptime I get the desired results (all four servers
respond with their uptimes). However, when I run a crawl only one
server, the host (which also acts as a slave), appears under the
nodes
display. This has happened after the primary server died and had now
been rebuilt. Had anyone experienced this before or does anyone have
any tips as to where to begin looking for the problem. Thanks.
