[jira] [Created] (PHOENIX-1849) MemoryLeak in PhoenixFlumePlugin PhoenixConnection

PeiLiping created PHOENIX-1849:
----------------------------------

             Summary: MemoryLeak in PhoenixFlumePlugin PhoenixConnection
                 Key: PHOENIX-1849
                 URL: https://issues.apache.org/jira/browse/PHOENIX-1849
             Project: Phoenix
          Issue Type: Bug
    Affects Versions: 4.3.0
         Environment: JDK 1.7 Flume 1.5.2 Phoenix 4.3.0 HBase 0.98
            Reporter: PeiLiping


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>();
