Table creation, though using "async" call to master, can actually run for a
while and cause RPC timeout
-------------------------------------------------------------------------------------------------------
Key: HBASE-3229
URL: https://issues.apache.org/jira/browse/HBASE-3229
Project: HBase
Issue Type: Bug
Components: client, master
Affects Versions: 0.90.0
Reporter: Jonathan Gray
Priority: Critical
Fix For: 0.90.0
Our create table methods in HBaseAdmin are synchronous from client POV.
However, underneath, we're using an "async" create and then looping waiting for
table availability. Because the create is async and we loop instead of block
on RPC, we don't expect RPC timeouts.
However, when creating a table with lots of initial regions, the "async" create
can actually take a long time (more than 30 seconds in this case) which causes
the client to timeout and gives impression something failed.
We should make the create truly async so that this can't happen. And rather
than doing one-off, inline assignment as it is today, we should reuse the fancy
enable/disable code stack just added to make this faster and more optimal.
