> Project: Phoenix
> Issue Type: Bug
> Affects Versions: 4.13.1
> Reporter: Flavio Pompermaier
> Assignee: Karan Mehta

> I'm using Phoenix 4.13 for CDH 5.11.2 parcel and enabling schemas made my
> code unusable.
> I think that this is not a bug of the CDH release, but of all 4.13.x releases.
> I have many parallel Phoenix connections and I always get the following
> exception:
> {code:java}
> Caused by: java.sql.SQLException:
> org.apache.hadoop.ipc.RemoteException(org.apache.hadoop.hbase.TableExistsException):
> SYSTEM:MUTEX
> at
> org.apache.phoenix.query.ConnectionQueryServicesImpl$12.call(ConnectionQueryServicesImpl.java:2492)

> at java.sql.DriverManager.getConnection(DriverManager.java:664)
> at java.sql.DriverManager.getConnection(DriverManager.java:270)
> {code}
> This is caused by the fact that all the times the SYSTEM tables are
> recreated, and this cannot be done simultaneously.
> Trying to debug the issue I found that in
> ConnectionQueryServicesImpl.createSysMutexTable() the call to
> getSystemTableNames() always return an empty array and the SYSTEM:MUTEX
> table is always recreated.
> This because getSystemTableNames() doesn't consider the case when system
> tables have namespace enabled. Right now that method tries to get all tables
> starting with *SYSTEM.\**, while it should try to get the list of *SYSTEM:\**
> tables..
> I hope this could get fixed very soon,
> Flavio
