Xiao Chen commented on HDFS-12116: ---------------------------------- patch 3 returned to a 5% failure :( Will take a closer look.... > BlockReportTestBase#blockReport_08 and #blockReport_08 intermittently fail > -------------------------------------------------------------------------- > > Key: HDFS-12116 > URL: https://issues.apache.org/jira/browse/HDFS-12116 > Project: Hadoop HDFS > Issue Type: Bug > Components: test > Affects Versions: 0.22.0 > Reporter: Xiao Chen > Assignee: Xiao Chen > Attachments: HDFS-12116.01.patch, HDFS-12116.02.patch, > HDFS-12116.03.patch, > TEST-org.apache.hadoop.hdfs.server.datanode.TestNNHandlesBlockReportPerStorage.xml > > > This seems to be long-standing, but the failure rate (~10%) is slightly > higher in dist-test run in using cdh. > In both _08 and _09 tests: > # an attempt is made to make a replica in {{TEMPORARY}} > state, by {{waitForTempReplica}}. > # Once that's returned, the test goes on to verify block reports shows > correct pending replication blocks. > But there's a race condition. If the replica is replicated between steps #1 > and #2, {{getPendingReplicationBlocks}} could return 0 or 1, depending on how > many replicas are replicated, hence failing the test. > Failures are seen on both {{TestNNHandlesBlockReportPerStorage}} and > {{TestNNHandlesCombinedBlockReport}} -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
