Hi,
I will think about it, but both the OpenJDK1.7 by OmniTI and the Oracle
JDK1.8 set the value to 256.
In case of problems I will check it again.

Just a quick observation here: the number of max file descriptors
configured is way too low in my opinion. Also, it has been few years since
last time I played with OpenSolaris but I'm going to assume that Illumos
you could run truss and the prstat commands and trace the jvm to see whats
going on. My guess, is that the JVM is spinning way too fast due the
ZooKeeper server. One way to test this theory is to start each process on
separate JVM and see how things behave.
cheers,

After switching away from OmniOS Java, did you still encounter similar
problem ?
If so, mind updating the thread with log / stack trace ?
Thanks

I checked and they are located in the same folder.
I found that java and jstack come from two different packages (java from
java and jstack from jdk), but they are both preinstalled with OmniOS,
maintained by OmniTI and compiled at the same time as the operating
system.
They should be 100% compatible.
I will ask the OmniOS mailing list.

Was the jstack of version 1.7.0_101 ?
I used google and found:
http://umchee.blogspot.com/p/i-recently-needed-to-investigate.html
but it was about Java 1.5
You can use this command to find the commandline for hbase process
(replace 16059
with the new process Id):
ps aux | grep 16059
Then use the jstack from same path as java to capture stack trace:

I'm not 100% sure about the stack trace (not a developer myself), but I
searched online and used jstack:

Additional info: after turning on DEBUG, the java process did not
immediately jump to 100% cpu as it used to do, it ramped up and it
took 3
minutes to get there. It may however be a coincidence.
Hope this can help pinpointing the issue.

Can you turn on DEBUG logging ?
In log4j.properties :
log4j.logger.org.apache.hadoop.hbase=DEBUG
Since this is reproducible, can you capture one or two stack traces
before
killing the server ?
Thanks

Hello,
I tested HBase with OpenTSDB some time ago on OS X locally and the
quickstart guide worked perfectly, merged with
http://opentsdb.net/setup-hbase.html where necessary.
I tried yesterday to do the same on my OmniOS/illumos server and I
encountered issues with HBase.
First of all I set "JAVA_HOME=/usr/java" in "conf/hbase-env.sh".
$ /usr/java/bin/java -version
openjdk version "1.7.0_101"
OpenJDK Runtime Environment (build 1.7.0_101-b00)
OpenJDK Server VM (build 24.101-b00, mixed mode)
I edited also "hbase-site.xml":
<configuration>
<property>
<name>hbase.rootdir</name>
<value>file:///export/home/olaf/hbase</value>
</property>
<property>
<name>hbase.zookeeper.property.dataDir</name>
<value>/export/home/olaf/zookeeper</value>
</property>
</configuration>
I then launched "bin/start-hbase.sh" and it quits apparently
normally.
A
directory "/export/home/olaf/zookeeper" appeared, but no
/export/home/olaf/hbase.
$ ls -l /export/home/olaf/
drwxrwxr-x 3 olaf olaf 3 Nov 12 01:16 zookeeper
I also checked with prstat ("top") and I see that java is taking a
full
CPU. After some minutes it's still crunching something.
If I launch "./bin/hbase shell" it never gets to
"hbase(main):001:0>".
At this point the only way is to kill -9 both java processes: the
stop
script doesn't work, it outputs dots forever.
I uploaded the two log files (.log and .out) to Pastebin:
http://pastebin.com/aFMXmWYU
I'm not sure where to begin with the debugging, since I did no
customisation at all and I don't see any error logged.
I would be grateful for some help.
Thanks
Olaf
