Hello Everyone,

 

Thanks for the help! I currently have a CDH 5.3 using AWS Quickstart. I am trying to create a simple table in hbase, but I am getting this error: 

 

ERROR: Can't get master address from ZooKeeper; znode data == null *EDIT see 1) *

 

I googled this error and it seems like its a configuration issue. However, I am using Cloudera and I'm guessing hdfs should already have the correct zookeeper path.

 

1) For some reason the Master for Hbase is down and we can't bring it back up. 

 

EDIT: I restarted the cluster and this issue is taken care of. Now I am getting this error...I believe this might be a step backward? 

 

 org.apache.hadoop.hbase.ipc.ServerNotRunningYetException: Server is not running yet

 

2) I saw that it went down the first time we stopped our cluster...is there a proper way to shut down our cluster? We went into our cluster and did the stop command...waited till all the services shut down and then stopped our AWS instances.

 

Thanks for the help!

 

Best,

 

Su
