Of course, if anyone has experience with hbase on OmniOS and has seen similar issues, or is successfully running previous versions, feel free to let me know. I haven't checked any previous version, I only tested the current stable.

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: <a href="http://pastebin.com/aFMXmWYU" rel="noreferrer" target="_blank">http://pastebin.com/aFMXmWYU</a> 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.
