Plamen Jeliazkov commented on HDFS-14059: ----------------------------------------- Apologies for the delay on this -- I ran into some difficulty in setup -- anyway, here is my testing experience: I tested in GCP with 6 nodes, all CentOS 7, 3 NameNodes (active + standby + obs), 3 DNs/NMs, in secure mode with 1 RM, 1 ZK, and (initially) ZKFCs on each NN that I eventually terminated. I tested initially as the hdfs user and then switched over to my own user and principal once things were stable: I ran the following simple scenarios: TestDFSIO - writing 3 x 5GB files. With a manual failover between the active and standby. TestDFSIO - appending 3 x 1GB files. With a manual failover between the active and standby. TestDFSIO - reading 3 x 5GB files. With 2 standby NNs and only the observer active during the read mappers -- it completed and went to reduce phase and needed active NN to complete. TeraGen/TeraSort/TeraValidate - no failover. During TeraValidate phase I ran with 2 observers and no active. So from my end things look good as far as ConfiguredFailoverProxy is concerned. I never experienced anything concerning around DelegationTokens and could confirm seeing them being generated and used by jobs. > Test reads from standby on a secure cluster with Configured failover > -------------------------------------------------------------------- > > Key: HDFS-14059 > URL: https://issues.apache.org/jira/browse/HDFS-14059 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: test > Reporter: Konstantin Shvachko > Assignee: Plamen Jeliazkov > Priority: Major > > Run standard HDFS tests to verify reading from ObserverNode on a secure HA > cluster with {{ConfiguredFailoverProxyProvider}}. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
