Wait for master before creating tables

[Kristoffer Sjögren <st...@gmail.com>]

Hi

Im doing an automated install of HBase cluster on EC2. But when the install
try to create tables (using hbase shell) the master often have not yet had
time start (since this operation is async), so these operations fail.

Is there a way to wait until the master is up and know when its safe to
 create tables? Maybe the table 'exists' and cluster 'status' operations
could be useful here?

Cheers,
-Kristoffer

Hi Kristoffer,

On the hbase shell, you already have a "status" command. Can you use
it? Or maybe look at the source code and do something similar? That
might allow you to see if master running as expected?
