Re: hbase java change baseZNode

[kevin]

val conf = HBaseConfiguration.create()
conf.set("hbase.zookeeper.property.clientPort", "2181")
conf.set("hbase.zookeeper.quorum", zkQuorum)
conf.set("zookeeper.znode.parent","/hbase-unsecure")

val connection = ConnectionFactory.createConnection(conf);

It's really worked.

As mentioned in Kevin's first email, if /hbase-unsecure is the znode used
by Ambari, setting zookeeper.znode.parent to hbase (or /hbase) wouldn't
help.

Re: hbase java change baseZNode

[Ted Yu]

How did your Java program obtain hbase-site.xml of the cluster ?

Looks like hbase-site.xml was not on the classpath.

hbase java change baseZNode

[kevin]

hi,all:
I install hbase by ambari ,I found it's zookeeper url is /hbase-unsecure .
when I use java api to connect to hbase ,program hung up .
after kill it ,I found message :
WARN ZKUtil: hconnection-0x4d1d2788-0x25617464bd80032,
quorum=Centosle02:2181,Centosle03:2181,Centosle01:2181, baseZNode=/hbase
Unable to get data of znode /hbase/meta-region-server
java.lang.InterruptedException

it read /hbase data not  /hbase-unsecure
