Dear Olaf, I have some problems when I try to install and launch the Hbase, I try to send a request e-mail to the relative e-mail box, but no one reply with me, are you kindly enough to tell me who give some reasonable technical support for HBase?
Thanks so much. -----Original Message----- From: Olaf Marzocchi [mailto:li...@marzocchi.net] Sent: Tuesday, November 15, 2016 6:19 AM To: user@hbase.apache.org Subject: Re: "Quickstart" on OmniOS/illumos not working, java eats CPU 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.
