> I got OOME after using the PhoenixFlumePlugin to write data into HBase for 6 hours. It looks like the  PhoenixConnection never release the prepare statements list even I call the commit method manually. 
> Now I had to close the connection after using the connection thousand times and recreate a new connection later.
> This issue is caused by the statements is never be cleared, so the fix could be clear the statements once the connection doesn't need them.
> Code:
> PhoenixConnection.java : 122 
> private List<SQLCloseable> statements = new ArrayList<SQLCloseable>();
