--------------------------------------
Summary: Fix Connection leak in mapred.TableOutputFormat when
spark uses it.
Key: HBASE-16117
URL: https://issues.apache.org/jira/browse/HBASE-16117
Project: HBase
Issue Type: Bug
Components: mapreduce
Affects Versions: 2.0.0, 1.3.0, 1.2.2, 1.1.6
Reporter: Jonathan Hsieh
Assignee: Jonathan Hsieh
Fix For: 2.0.0, 1.3.0, 1.2.2, 1.1.6
Spark seems to instantiate multiple instances of output formats within a single
process. When mapred.TableOutputFormat (not mapreduce.TableOutputFormat) is
used, this may cause connection leaks that slowly exhaust the cluster's zk
connections.
This patch fixes that.
