-1 Keith and I tested the continuous ingest with agitation on 11 nodes (9 workers) for 24 hrs and noticed the following after running the MapReduce verify job. The "undefined" counter is greater than 0 may be indicating data loss.
org.apache.accumulo.test.continuous.ContinuousVerify$Counts REFERENCED=35470816664 * UNDEFINED=707335949* UNREFERENCED=715995424 The cluster was setup using Muchos (https://github.com/apache/fluo-muchos) & following are the details * 11 Azure VMs (Standard D8s) * Managed Disk – 3 x 1024g per VM * Hadoop 2.10.0 * Accumulo 1.10.0-rc2 * Java 8 * CentOS7.5 Created the table 'ci' and split using the below commands $ accumulo org.apache.accumulo.test.continuous.GenSplits 90 > splits.txt $ accumulo shell -u root -p secret -e 'createtable ci -sf splits.txt' Below is the agitator options used for the test nohup ./tserver-agitator.pl 1:10 1:10 1 3 > logs/tserver-ag.out 2> logs/tserver-ag.err & We will investigate the data loss and share our findings.
