I managed fix this issue on my machine. If you notice the startup script of
*local* regionservers (bin/local-regionservers.sh).
run_regionserver () {
DN=$2
export HBASE_IDENT_STRING="$USER-$DN"
HBASE_REGIONSERVER_ARGS="\
-D hbase.regionserver.port=`expr 16200 + $DN` \
-D hbase.regionserver.info.port=`expr 16300 + $DN`"
"$bin"/hbase-daemon.sh --config "${HBASE_CONF_DIR}" $1 regionserver
$HBASE_REGIONSERVER_ARGS
}
We put hbase.regionserver.port = 16200 + num (1 for localhost) and we call
this script as follows
regionservers=`cat "$HOSTLIST"`
if [ "$regionservers" = "localhost" ]; then <-- This line
"$bin"/local-regionservers.sh start 1
So bottomline is you *must* have "localhost" in conf/regionservers (no
hostnames or FQDN) and as per HBASE-12263 your "hostname -f" *should not*
resolve to a localhost. Otherwise you see something like
2014-11-30 12:33:23,230 FATAL [main] regionserver.RSRpcServices: The
hostname of regionserver cannot be set to localhost in a fully-distributed
setup because it won't be reachable. See "Getting Started" for more
information.
2014-11-30 12:33:23,231 ERROR [main] regionserver.HRegionServerCommandLine:
Region server exiting
Set it using DNS or hack the /etc/hosts file.
Thanks,
