Did you confirm that 9090 is not occpied?
For example, using following command: ``` [root@cdh-master ~]# netstat -anp | grep LISTEN | grep 9090 tcp 0 0 0.0.0.0:9090 0.0.0.0:* LISTEN 32274/java [root@cdh-master ~]# [root@cdh-master ~]# jps -mlv | grep 32274 32274 org.apache.hadoop.hbase.thrift.ThriftServer start --port 9090 -threadpool --bind 0.0.0.0 -Dproc_thrift -XX:OnOutOfMemoryError=kill -9 %p -Djava.net.preferIPv4Stack=true -Xms1073741824 -Xmx1073741824 -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -XX:CMSInitiatingOccupancyFraction=70 -XX:+CMSParallelRemarkEnabled -XX:OnOutOfMemoryError=/usr/lib64/cmf/service/common/killparent.sh -Dhbase.log.dir=/var/log/hbase -Dhbase.log.file=hbase-cmf-hbase-HBASETHRIFTSERVER-cdh-master.log.out -Dhbase.home.dir=/opt/cloudera/parcels/CDH-5.7.6-1.cdh5.7.6.p0.6/lib/hbase -Dhbase.id.str= -Dhbase.root.logger=INFO,RFA -Djava.library.path=/opt/cloudera/parcels/CDH-5.7.6-1.cdh5.7.6.p0.6/lib/hadoop/lib/native:/opt/cloudera/parcels/CDH-5.7.6-1.cdh5.7.6.p0.6/lib/hbase/lib/native/Linux-amd64-64 -Dhbase.security.logger=INFO,NullAppender ``` Besides, I guess using user mailing maybe more suitable. -- Best wishes to you !
