------------------------------------
Summary: HBase Connection leak in Phoenix MR Jobs
Key: PHOENIX-4489
URL: https://issues.apache.org/jira/browse/PHOENIX-4489
Project: Phoenix
Issue Type: Bug
Reporter: Karan Mehta
Phoenix MR jobs uses a custom class {{PhoenixInputFormat}} to determine the
splits and the parallelism of the work. The class directly opens up a HBase
connection, which is not closed after the usage. Independently running MR jobs
should not have any concern, however jobs that run through Phoenix-Spark can
cause leak issues if this is left unclosed (since those jobs run as a part of
same JVM).
Apart from this, the connection should be instantiated with
{[HBaseFactoryProvider.getHConnectionFactory()}} instead of the default one. It
can be useful if a separate client is trying to run jobs and wants to provide a
custom implementation of {{HConnection}}.
[~jmahonin] Any ideas?
[~jamestaylor] [~vincentpoon] Any concerns around this?
