> Observed the significant increase in ZK connection on performance testing on map reduce jobs. Turns out the [TableOutputFormat.checkOutputSpecs()|https://github.com/apache/hbase/blob/master/hbase-mapreduce/src/main/java/org/apache/hadoop/hbase/mapreduce/TableOutputFormat.java#L182] is not closing the connection it uses to get the hbase admin. It closes the hbase admin but never close the connection to get the admin.
