Josh Mahonin commented on PHOENIX-4319: --------------------------------------- I've not, but we're still woefully behind on our Phoenix versions at $DAYJOB If the issue is only seen in Phoenix 4.10 and onwards, _perhaps_ there's a regression involved with PHOENIX-3600? To revert to the pre-4.10 behaviour, the server-side setting {{phoenix.mapreduce.split.by.stats}} can be set to false. > Zookeeper connection should be closed immediately > ------------------------------------------------- > > Key: PHOENIX-4319 > URL: https://issues.apache.org/jira/browse/PHOENIX-4319 > Project: Phoenix > Issue Type: Bug > Affects Versions: 4.10.0 > Environment: phoenix4.10 hbase1.2.0 > Reporter: Jepson > Labels: patch > Original Estimate: 48h > Remaining Estimate: 48h > > *Code:* > {code:java} > val zkUrl = "192.168.100.40,192.168.100.41,192.168.100.42:2181:/hbase" > val configuration = new Configuration() > configuration.set("hbase.zookeeper.quorum",zkUrl) > val spark = SparkSession > .builder() > .appName("SparkPhoenixTest1") > .master("local[2]") > .getOrCreate() > for( a <- 1 to 100){ > val wms_doDF = spark.sqlContext.phoenixTableAsDataFrame( > "DW.wms_do", > Array("WAREHOUSE_NO", "DO_NO"), > predicate = Some( > """ > |MOD_TIME >= TO_DATE('begin_day', 'yyyy-MM-dd') > |and MOD_TIME < TO_DATE('end_day', 'yyyy-MM-dd') > """.stripMargin.replaceAll("begin_day", > "2017-10-01").replaceAll("end_day", "2017-10-25")), > conf = configuration > ) > wms_doDF.show(100) > } > {code} > *Description:* > The connection to zookeeper is not getting closed,which causes the maximum > number of client connections to be reached from a host( we have > maxClientCnxns as 500 in zookeeper config). > *Zookeeper connections:* > [https://github.com/Hackeruncle/Images/blob/master/zookeeper%20connections.png] > *Reference:* > [https://community.hortonworks.com/questions/116832/hbase-zookeeper-connections-not-getting-closed.html] -- This message was sent by Atlassian JIRA (v6.4.14#64029)
