I notice we don't close the PreparedStatement at
https://github.com/apache/phoenix/blob/master/phoenix-flume/src/main/java/org/apache/phoenix/flume/serializer/RegexEventSerializer.java#L72
. I will work on providing a patch soon.
> 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
> Assignee: maghamravikiran
> Fix For: 4.8.0
>
>
> 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>();
