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:
{noformat}
launch-hbase-cluster testcluster 100 5
{noformat}
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.
