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:

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
