Subject [jira] Created: (HBASE-1961) HBase EC2 scripts
Date Sat, 07 Nov 2009 18:15:33 GMT
HBase EC2 scripts

                 Key: HBASE-1961
                 URL: https://issues.apache.org/jira/browse/HBASE-1961
             Project: Hadoop HBase
          Issue Type: New Feature
         Environment: Amazon AWS EC2
            Reporter: Andrew Purtell
            Priority: Minor
             Fix For: 0.21.0, 0.20.3

Attached tarball is a clone of the Hadoop EC2 scripts, modified significantly to start up
a HBase storage only cluster on top of HDFS backed by instance storage. 

Tested with the HBase 0.20 branch but should work with trunk also. Only the AMI create and
launch scripts are tested. Will bring up a functioning HBase cluster. 

Do "create-hbase-image c1.xlarge" to create an x86_64 AMI, or "create-hbase-image c1.medium"
to create an i386 AMI.  Public Hadoop/HBase 0.20.1 AMIs are available:
    i386: ami-c644a7af
    x86_64: ami-f244a79b

launch-hbase-cluster brings up the cluster: First, a small dedicated ZK quorum, specifiable
in size, default of 3. Then, the DFS namenode (formatting on first boot) and one datanode
and the HBase master. Then, a specifiable number of slaves.  For example:

    launch-hbase-cluster testcluster 100 5

would bring up a cluster with 100 slaves supported by a 5 node ZK ensemble.

We must colocate a datanode with the namenode because currently the master won't tolerate
a brand new DFS with only namenode and no datanodes up yet. See HBASE-1960. By default the
launch scripts provision ZooKeeper as c1.medium and the HBase master and region servers as
c1.xlarge. The result is a fixed size HBase cluster supported by a ZooKeeper ensemble. ZK
ensembles are not dynamic, but HBase clusters can be grown by simply starting up more slaves,
just like Hadoop.
