Hudson commented on HBASE-15617: -------------------------------- SUCCESS: Integrated in HBase-1.2 #628 (See [https://builds.apache.org/job/HBase-1.2/628/]) HBASE-15617 Canary in regionserver mode might not enumerate all (apurtell: rev 8108fc8643eef1b11fbaefee98b03651fff38bd0) * hbase-server/src/test/java/org/apache/hadoop/hbase/tool/TestCanaryTool.java * hbase-server/src/main/java/org/apache/hadoop/hbase/tool/Canary.java > Canary in regionserver mode might not enumerate all regionservers > ----------------------------------------------------------------- > > Key: HBASE-15617 > URL: https://issues.apache.org/jira/browse/HBASE-15617 > Project: HBase > Issue Type: Bug > Affects Versions: 2.0.0 > Reporter: Andrew Purtell > Assignee: Sanjeev Lakshmanan > Priority: Minor > Labels: beginner > Fix For: 2.0.0, 1.3.0, 1.2.2, 0.98.20 > > Attachments: HBASE-15617-v1.patch, HBASE-15617.patch > > > When running in regionserver mode the Canary is expected to probe for service > health one time per regionserver during a probe interval. > Each time the canary chore fires, we create a RegionServerMonitor, which uses > filterRegionServerByName (via getAllRegionServerByName) to enumerate over all > table descriptors, find the locations for each table, then assemble the list > of regionservers to probe from this result. The list may not contain all live > regionservers, if there is a regionserver up but for some reason not serving > any regions. To ensure we have the complete list of live regionservers I > think it would be better to use Admin#getClusterStatus and enumerate the live > server list returned in the result. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
