Terry Porter updated ACCUMULO-1901:
-----------------------------------
Description:
Even when a second host is listed in the gc file, the gc process is only ever
started on the first host listed in the gc file. The issue lies in lines 48-55
in start-here.sh as shown below:
{code}
for host in $HOSTS
do
if [ ${host} = ${GC} ]
then
${bin}/start-server.sh $GC gc "garbage collector"
break
fi
done
{code}
Simple fix:
{code}
for host in $HOSTS
do
if grep -q "^${host}\$" $ACCUMULO_HOME/conf/gc
then
${bin}/start-server.sh ${host} gc "garbage collector"
break
fi
done
{code}
This fix works in my 1.4.2 environment. stop-here.sh already sweeps all
possible processes to kill them, so I assumed no fix was needed there, but on
my last cluster shutdown I found the stop-all.sh script only stopped the GC on
the Master host. That fix is still outstanding.

I posted the fix in case anyone needs this ASAP as this will be my first
development work with an open source project, but I hope to be able to post the
fix this weekend.
