Change subject: IMPALA-13047: Support restarting/killing specified impalads in start-impala-cluster.py ...................................................................... IMPALA-13047: Support restarting/killing specified impalads in start-impala-cluster.py This patch adds a new option, --impalad_ids, in start-impala-cluster.py to specify the impalads to restart/kill. It's a comma seperated list of the impalad index, starting from 0. Assuming the current cluster has 3 impalads, to restart the first impalad: bin/start-impala-cluster.py -r --impalad_ids=0 To restart the second and third impalad: bin/start-impala-cluster.py -r --impalad_ids=1,2 To kill the last impalad: bin/start-impala-cluster.py --kill --impalad_ids=2 To be simple, it's not allowed to change the cluster size (by -s) in the same command. This patch also adds logs to show which process is killed, e.g. 17:33:33 MainThread: Killed statestored (pid 6618) 17:33:33 MainThread: Killed catalogd (pid 6676) 17:33:33 MainThread: Killed impalad (pid 6726) 17:33:33 MainThread: Killed impalad (pid 6729) Tests: - Verified the commands locally Change-Id: Id4a863853341959eb6870b662d82188e7d570971 --- M bin/start-impala-cluster.py 1 file changed, 70 insertions(+), 21 deletions(-) git pull ssh://gerrit.cloudera.org:29418/Impala-ASF refs/changes/76/21376/1 -- To view, visit http://gerrit.cloudera.org:8080/21376 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-MessageType: newchange Gerrit-Change-Id: Id4a863853341959eb6870b662d82188e7d570971 Gerrit-Change-Number: 21376 Gerrit-PatchSet: 1 Gerrit-Owner: Quanlong Huang <huangquanl...@gmail.com>
