Hoss Man updated SOLR-7693:
---------------------------
Description:
If bin/solr is used on a system which does not have lsof available a code path
is used when starting up solr nodes that causes bin/solr to exist as soon as
the first solr node is launched.
the work around is to either install lsof, or manually start up each of the
additional nodes, and create the collection, after the "-e cloud" command
exits...
{code}
solr start -cloud -s example/cloud/node2/solr -p XXXX -z localhost:9983
solr start -cloud -s example/cloud/node3/solr -p YYYY -z localhost:9983
...
bin/solr create -c gettingstarted -replicationFactor N -shards M -d
data_driven_schema_configs
{code}
Original bug report...

Extract from the command prompt on starting up solr cloud :
-------------------------------------------------------------------------------------------
[appuser@mysolrsandbox ~]$ cd $HOME/softwares/solr-5.2.1
[appuser@mysolrsandbox solr-5.2.1]$ bin/solr start -e cloud -noprompt -m 1g
Welcome to the SolrCloud example!
Starting up 2 Solr nodes for your example SolrCloud cluster.
Creating Solr home directory
/home/appuser/softwares/solr-5.2.1/example/cloud/node1/solr
Cloning Solr home directory
/home/appuser/softwares/solr-5.2.1/example/cloud/node1 into
/home/appuser/softwares/solr-5.2.1/example/cloud/node2
Starting up SolrCloud node1 on port 8983 using command:
solr start -cloud -s example/cloud/node1/solr -p 8983 -m 1g
Started Solr server on port 8983 (pid=102). Happy searching!
[appuser@mysolrsandbox solr-5.2.1]$
------------------------------------------------------------------------------------------------
The second node is not starting up.
Possible issue :
File : $SOLR_HOME/bin/solr
Line number : 1431
-- The "exit;" command is causing the shell scrip to exit.
Line 1428 - 1432

SOLR_PID=`ps auxww | grep start\.jar | grep -w $SOLR_PORT | grep -v grep
| awk '{print $2}' | sort -r`
echo -e "\nStarted Solr server on port $SOLR_PORT (pid=$SOLR_PID). Happy
searching!\n"
exit;

Work Around :
Comment line 1431 in the shell script

Summary: "bin/solr start -e cloud" will not work if lsof is not
installed - script exits as soon as 1st node is started (was: bin/solr start
-e cloud -noprompt on a docker container spins only one node instead of two)
Ah.... yes, the part i was overlooking is that a sub-shell *is* used in the
lsof case.
updated summary &description to clarify root cause (systems w/o lsof) and list
workarround.
