Version 1.2.6, rUnknown, Mon May 29 02:25:32 CDT 2017
Yet I did the advised settings Apache gave in order to make the data persitent
I tried to run a status
and it gave me back :
2017-11-30 17:26:15,464 ERROR [main] client.ConnectionManager$HConnectionImplementation: Can't get connection to ZooKeeper: KeeperErrorCode = ConnectionLoss for /hbase
I found a similar question on SO which states that the error indicates that zookeeper quorum is not running – most probable cause can be some inconsistency with your zookeeper.quorum setting in conf/hbase-site.xml
but it didn't helped my conf/hbase-side.xml
file looks like :
<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>
<configuration>
<property>
<name>hbase.rootdir</name>
<value>file:///DataHbase/hbase</value>
</property>
<property>
<name>hbase.zookeeper.property.dataDir</name>
<value>/DataHbase/zookeeper</value>
</property>
</configuration>
Best Answer
I got a similar error in dev environment, then I added
export HBASE_MANAGES_ZK=true
to conf/hbase-env.sh and it started working for me. Source - https://askubuntu.com/a/599094 and https://stackoverflow.com/a/22664366
