What is ZK security group? (I know very little of zookeeper) I thought the following zookeeper props set these up
zookeeper.servers=domU-12-31-39-06-29-91.compute-1.internal:2888:3888 zookeeper.clientPort=2181 do I have to set them up in Hbase too (even though that's the default)? -----Original Message----- From: Andrew Purtell [mailto:apurt...@apache.org] Sent: Sunday, August 02, 2009 10:13 PM To: hbase-user@hadoop.apache.org Subject: Re: problem starting Hbase 0.20 with Katta on EC2 Hi, Have you set up the security group for your instances to allow the Zookeeper quorum peers to communicate with each other and clients? You need to allow all instances to communicate with each other on the following ports: 2181: client 2888: replication 3888: leader election The above are the defaults. All can be changed via various settings in hbase-site.xml (see hbase-default.xml). - Andy ________________________________ From: Yair Even-Zohar <ya...@audiencescience.com> To: hbase-user@hadoop.apache.org; katta-develo...@lists.sourceforge.net Sent: Sunday, August 2, 2009 11:57:40 AM Subject: problem starting Hbase 0.20 with Katta on EC2 I have the following problem when trying to run hbase 0.20 on ec2.

Server name is correct, client port is 2181 and user is root. Any help? Thanks -Yair
