Hi All, While investigating IMPALA-5598 I added a counter with the total number of threads to /threadz. See below for what it looks like (I hope the ASF mailer won't eat the format). Does this look helpful? If someone thinks it does, I'll create a JIRA and push the change.
Thanks, Lars Thread GroupsAll threads <http://lv-desktop.ca.cloudera.com:25000/thread-group?all>DataStreamSender : (running: 0, total created: 2500) <http://lv-desktop.ca.cloudera.com:25000/thread-group?group=DataStreamSender>common : (running: 2, total created: 2) <http://lv-desktop.ca.cloudera.com:25000/thread-group?group=common>coordinator-fragment-rpc : (running: 12, total created: 12) <http://lv-desktop.ca.cloudera.com:25000/thread-group?group=coordinator-fragment-rpc>disk-io-mgr : (running: 34, total created: 34) <http://lv-desktop.ca.cloudera.com:25000/thread-group?group=disk-io-mgr>fragment-mgr : (running: 0, total created: 2550) <http://lv-desktop.ca.cloudera.com:25000/thread-group?group=fragment-mgr>hdfs-scan-node : (running: 0, total created: 2500) <http://lv-desktop.ca.cloudera.com:25000/thread-group?group=hdfs-scan-node>hdfs-worker-pool : (running: 16, total created: 16) <http://lv-desktop.ca.cloudera.com:25000/thread-group?group=hdfs-worker-pool>impala-server : (running: 8, total created: 8) <http://lv-desktop.ca.cloudera.com:25000/thread-group?group=impala-server>plan-fragment-executor : (running: 0, total created: 2550) <http://lv-desktop.ca.cloudera.com:25000/thread-group?group=plan-fragment-executor>query-exec-state : (running: 0, total created: 50) <http://lv-desktop.ca.cloudera.com:25000/thread-group?group=query-exec-state>rpc-pool : (running: 8, total created: 8) <http://lv-desktop.ca.cloudera.com:25000/thread-group?group=rpc-pool>scheduling : (running: 1, total created: 1) <http://lv-desktop.ca.cloudera.com:25000/thread-group?group=scheduling>setup-server : (running: 2, total created: 2) <http://lv-desktop.ca.cloudera.com:25000/thread-group?group=setup-server>statestore-subscriber : (running: 1, total created: 1) <http://lv-desktop.ca.cloudera.com:25000/thread-group?group=statestore-subscriber>thrift-server : (running: 248, total created: 248) <http://lv-desktop.ca.cloudera.com:25000/thread-group?group=thrift-server>
