stack commented on HBASE-7840:
------------------------------
What is this comment in ClusterManager.java?
{code}
+ // Not in ClusterManager because it uses 'exec'
{code}
Bit odd this is all hardcoded into the script:
{code}
+ cmd += "export HBASE_REGIONSERVER_OPTS='" +
+ jmx +
+ "-server -XX:ParallelGCThreads=4 -XX:+UseParNewGC -Xmn512m " +
+ "-XX:CMSInitiatingOccupancyFraction=80 -verbose:gc
-XX:+PrintGCDetails " +
+ "-XX:PrintFLSStatistics=1 -XX:+PrintPromotionFailure " +
+ "-XX:+PrintGCTimeStamps -XX:+PrintGCDateStamps -Xloggc:" +
+ getHBaseHome() + "/logs/gc-" + service + ".log " +
+ "-Xms" + heapSize + "m -Xmx" + heapSize + "m -XX:ErrorFile=" +
+ getHBaseHome() + "/logs/gc-" + service + "-err.log" +
+ "'; ";
{code}
Woah!!! Rad:
{code}
+ toExec += "sudo /sbin/iptables -A INPUT -i lo -j ACCEPT;";
+ toExec += "sudo /sbin/iptables -A OUTPUT -o lo -j ACCEPT;";
+ toExec += "sudo /sbin/iptables -A INPUT -p tcp -s 0/0 -d " + hostname +
+ " --sport 513:65535 --dport 22 -m state --state NEW,ESTABLISHED -j
ACCEPT;";
+ toExec += "sudo /sbin/iptables -A OUTPUT -p tcp -s " + hostname +
+ " -d 0/0 --sport 22 --dport 513:65535 -m state --state ESTABLISHED -j
ACCEPT;";
+ toExec += "sudo /sbin/iptables -P INPUT DROP;";
+ toExec += "sudo /sbin/iptables -P OUTPUT DROP;";
+ toExec += "sudo /sbin/iptables -P FORWARD DROP;";

I skimmed the patch. These are some really great tests. Do they work? +1 on
commit if they do (even if above freaks me out -- smile)
