Hbase version is 2.2.0, it run in Ubuntu 16.04 LTS.
When I take Hbase in standalone mode, in fact what else any mode, I got some "Connection refused" error like below
2019-06-22 00:28:12,804 INFO [main-SendThread(127.0.0.1:2181)] zookeeper.ClientCnxn: Opening socket connection to server 127.0.0.1/127.0.0.1:2181. Will not attempt to authenticate using SASL (unknown error)

It always repeat again and again.
My hbase-site.xml:
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>hbase.rootdir</name>
<value>file:///usr/local/hbase/tmp/data</value>
</property>
<property>
<name>hbase.cluster.distributed</name>
<value>false</value>
</property>
</configuration>
And 'hbase-env.sh' file which i just config JAVA_HOME and HBASE_MANAGES_ZK:
export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64
export HBASE_MANAGES_ZK=true
I can not find my configuration error. When I type start-hbase.sh command, then I can see the "Hbase DATA in Hbase home" and the HMaster already running when I type 'jps' command.
But, when I type hbase shell, I fail to connect.
I can not find any solution ways in master-log, because it always repeat "Connection refused".
I can not figure out where the problem is.
I have solved this problem. The specific reason is that my 'hbase' library depend 'hadoop', version 2.8.5, but my deployed 'hadoop' version is 3.1.0. So it lead to that 'hflush/hsync' of 'hbase' is unsupported.
The solutions are here
