Daniel Vimont commented on HBASE-14879:
---------------------------------------
What we are experiencing seems to be the standard behavior of the
HBaseTestingUtility.
The problem can be replicated through execution of a single line of code:
{code}
new HBaseTestingUtility().startMiniCluster();
{code}
This results in the following output, regarding the 'hbase:namespace'
metatable, which the miniCluster is apparently in the process of creating when
this message is issued:
{code}
2016-05-12 12:45:33,413 ERROR [ProcedureExecutor-0] master.TableStateManager:
Unable to get table hbase:namespace state
org.apache.hadoop.hbase.TableNotFoundException: hbase:namespace
{code}
----
To more fully replicate what WE are experiencing (a series of those same ERROR
messages when a user table is created), the following three lines of code may
be executed:
{code}
final HBaseTestingUtility TEST_UTIL = new HBaseTestingUtility();
TEST_UTIL.startMiniCluster();
TEST_UTIL.createTable(TableName.valueOf("table1"), Bytes.toBytes("cf1"));
{code}
This results in the following output:
{code}
2016-05-12 12:56:54,052 ERROR [ProcedureExecutor-0] master.TableStateManager:
Unable to get table hbase:namespace state
org.apache.hadoop.hbase.TableNotFoundException: hbase:namespace
...
2016-05-12 12:56:56,496 ERROR [ProcedureExecutor-3] master.TableStateManager:
Unable to get table table1 state
org.apache.hadoop.hbase.TableNotFoundException: table1
...
2016-05-12 12:56:56,550 ERROR
[B.defaultRpcServer.handler=11,queue=2,port=38763] master.TableStateManager:
Unable to get table table1 state
org.apache.hadoop.hbase.TableNotFoundException: table1
{code}
As you can see, whenever a *user* table is created (as opposed to a system
metatable), a similar ERROR message is issued twice in the course of table
creation.
