Hi Suraj Thank you !
hbase-env.sh is follow: # The java implementation to use. Java 1.6 required. # export JAVA_HOME=/usr/java/jdk1.6.0/ export JAVA_HOME=/etc/java-config-2/current-system-vm In addition , $ java-config -L The following VMs are available for generation-2: 1) IcedTea6-bin 1.7.2 [icedtea6-bin] *) Sun JDK 1.6.0.20 [sun-jdk-1.6] VMs marked as Build Only may contain Security Vulnerabilities and/or be EOL. Gentoo recommends not setting these VMs as either your System or User VM. Please see http://www.gentoo.org/doc/en/java.xml#build-only for more information I guess that it worked well when I used IcedTea6,because I changed the JDK to Sun JDK from IcedTea6 at about 3 days ago. 2010/12/20 Suraj Varma <[email protected]> > Can you check if your conf/hbase-env.sh is explicitly setting the JAVA_HOME > to the below 1.6.0_20 JRE?
