Rushabh S Shah updated HDFS-11804: ---------------------------------- Status: Open (was: Patch Available) > KMS client needs retry logic > ---------------------------- > > Key: HDFS-11804 > URL: https://issues.apache.org/jira/browse/HDFS-11804 > Project: Hadoop HDFS > Issue Type: Bug > Affects Versions: 2.6.0 > Reporter: Rushabh S Shah > Assignee: Rushabh S Shah > Attachments: HDFS-11804-trunk-1.patch, HDFS-11804-trunk-2.patch, > HDFS-11804-trunk-3.patch, HDFS-11804-trunk-4.patch, HDFS-11804-trunk-5.patch, > HDFS-11804-trunk.patch > > > The kms client appears to have no retry logic – at all. It's completely > decoupled from the ipc retry logic. This has major impacts if the KMS is > unreachable for any reason, including but not limited to network connection > issues, timeouts, the +restart during an upgrade+. > This has some major ramifications: > # Jobs may fail to submit, although oozie resubmit logic should mask it > # Non-oozie launchers may experience higher rates if they do not already have > retry logic. > # Tasks reading EZ files will fail, probably be masked by framework reattempts > # EZ file creation fails after creating a 0-length file – client receives > EDEK in the create response, then fails when decrypting the EDEK > # Bulk hadoop fs copies, and maybe distcp, will prematurely fail -- 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
