Phoenix and ZK connection issue

cui_lin — Wed, 16 Dec 2015 06:45:00 GMT

I tried Phoenix and installed it according to the instruction, but I got the following error message:

[root@cui-hdp-02 phoenix]# sqlline.py localhost Setting property: [isolation, TRANSACTION_READ_COMMITTED] issuing: !connect jdbc:phoenix:localhost none none org.apache.phoenix.jdbc.PhoenixDriver Connecting to jdbc:phoenix:localhost

15/12/15 14:17:14 WARN util.NativeCodeLoader: Unable to load native-hadoop library for your platform... using builtin-java classes where applicable

15/12/15 14:17:14 WARN impl.MetricsConfig: Cannot locate configuration: tried hadoop-metrics2-phoenix.properties,hadoop-metrics2.properties 15/12/15 14:17:15 ERROR client.ConnectionManager$HConnectionImplementation: The node /hbase is not in ZooKeeper. It should have been written by the master. Check the value configured in 'zookeeper.znode.parent'. There could be a mismatch with the one configured in the master.

My hbase's znode is by default defined as /hbase-unseure. How can i change phoenix to use current znode, instead of /hbase?

Trying providing an argument of "localhost:2181:/hbase-unsecure" instead of "localhost"

You can use the sqlline like this:

sqlline.py localhost:2181:/hbase-unsecure

You have to create links in the directory where `sqlline.py` lives to 2 .xml files that are provided by HBase/Hadoop.

$ pwd
/usr/hdp/2.2.8.0-3150/phoenix/bin
$ ll | grep xml
lrwxrwxrwx 1 root root   29 Dec 16 13:34 core-site.xml -> /etc/hbase/conf/core-site.xml
lrwxrwxrwx 1 root root   30 Dec 16 13:34 hbase-site.xml -> /etc/hbase/conf/hbase-site.xml

With those in place and `$JAVA_HOME` and `java` on your `$PATH`, you can now run `sqlline.py`:

$ ./sqlline.py localhost:2181/hbase-unsecure
