Weird HBase Error

avatar
Master Guru

I have code I have been using for a while and has worked.

But today my Java code calling Phoenix, ran into this:

: Initiating client connection, connectString=tspann:2181 sessionTimeout=90000 watcher=hconnection-0x4550bb580x0, quorum=tspann:2181, baseZNode=/hbase-unsecure 2016-12-15 16:49:44.898 INFO 11624 --- [42.140.21:2181)] org.apache.zookeeper.ClientCnxn : Opening socket connection to server 24221/242.21:2181. Will not attempt to authenticate using SASL (unknown error)

That is not a real error. ZK is just saying that it won't do SASL when connecting to the server (because this is not a secure cluster). You can ignore it.

This is just an information message during the connection. If your application doesn't work, check that zookeeper as well as HBase are started.
