Hi everybody, the Analytics Hadoop upgrade to Java 8 has been postponed due to unexpected hw failures (https://phabricator.wikimedia.org/T187164 and https://phabricator.wikimedia.org/T187162) happened this morning and causing some HDFS blocks to be under replicated/corrupted. To be on the safe side, we'll wait for the cluster's metrics to fully recover before doing anything. I will update this email thread as soon as we'll be ready, but it this might happen in EU late evening / SF morning.
Sorry for the delay! The Analytics Hadoop cluster staged a rebellion for Java 8, but we'll eventually succeed :) Luca 2018-02-05 19:48 GMT+01:00 Joseph Allemandou <jalleman...@wikimedia.org>: > Hi Analytics folks, > > *TL;DR: Hadoop cluster maintenance postponed to Tue 13th February* > > We've experienced an issue in getting some data onto the cluster this > month, making some of our monthly datasets (the ones that depend on that > late data) not yet computed. > We have decided to postpone the maintenance of the cluster to next week, > allowing for those jobs to be finished. > We are very sorry about the short notice and will send another email the > day before maintenance. > Best > > Joseph Allemandou on behalf of the Analytics-Team > Data Engineer @ Wikimedia Foundation > IRC: joal > > _______________________________________________ > Engineering mailing list > engineer...@lists.wikimedia.org > https://lists.wikimedia.org/mailman/listinfo/engineering > > _______________________________________________ Wiki-research-l mailing list Wikifirstname.lastname@example.org https://lists.wikimedia.org/mailman/listinfo/wiki-research-l
